Introduction
Sunstone is a plagioclase feldspar, which when viewed from certain directions exhibits a brilliant, spangled appearance, this has led to its use as a gemstone. Chemically it is identified as Na2O Al2O3 6SiO2 + CaO7, Al2O3 2SiO2. It is a mixture of sodium, aluminum, silicon, calcium and oxygen. It comes in numerous colors including blue, grey, white, pink, green, and brown. It exhibits uneven conchoidal fracture with a hardness of 6. It possesses opalescent luster with a white streak, specific gravity of 2.61, and a refractive index of 1.72. The optical effect appears to be due to reflections from inclusions of red copper, in the form of minute scales, which are hexagonal, rhombic, or irregular in shape, and are disposed parallel to the principal cleavage plane. These inclusions give the stone an appearance something like that of aventurine, hence sunstone is known also as Aventurine- feldspar. The optical effect is called Shiller and the color of Oregon Sunstone is due to copper. In the middle part of this crystal, it sparks a lot, and usually has a dark color in the middle, and the color becomes lighter as it becomes the outer part. It has been found in Southern Norway and some United States localities. It is the official gemstone of Oregon. Sunstone was not common until recently. Previously the best-known locality was Tvedestrand, near Arendal, in south Norway, where masses of the sunstone occur embedded in a vein of quartz running through gneiss. Due to the discovery of large deposits in Oregon, Sunstone is now readily available. Other locations include near Lake Baikal in Siberia, and several United States localities notably at Middletown Township, Delaware County, Pennsylvania, Lakeview, Oregon, and Statesville, North Carolina.
सनस्टोन एक प्लाजियोक्लेज़ फेल्डस्पार है, जो कुछ दिशाओं से देखने पर एक शानदार, उपस्थिति प्रदर्शित करता है | इससे इसका उपयोग रत्न के रूप में होने लगा है। रासायनिक रूप से इसकी पहचान Na2O Al2O3 6SiO2 + CaO7, Al2O3 2SiO2 के रूप में की जाती है। यह सोडियम, एल्यूमीनियम, सिलिकॉन, कैल्शियम और ऑक्सीजन का मिश्रण है। यह नीले, भूरे, सफेद, गुलाबी, हरे और भूरे सहित कई रंगों में आता है। यह 6 की कठोरता के साथ असमान से शंकुधारी फ्रैक्चर को प्रदर्शित करता है। इसमें सफेद लकीर के साथ ओपलेसेंट चमक, 2.61 का विशिष्ट गुरुत्व और 1.72 का अपवर्तक सूचकांक होता है। ऑप्टिकल प्रभाव सूक्ष्म तराजू के रूप में लाल तांबे के समावेशन से प्रतिबिंब के कारण प्रतीत होता है, जो हेक्सागोनल, रोम्बिक या अनियमित आकार के होते हैं, और मुख्य दरार-तल के समानांतर स्थित होते हैं। ये समावेशन पत्थर को कुछ हद तक एवेन्ट्यूरिन जैसा दिखता है, इसलिए सनस्टोन को एवेंट्यूरिन-फ़ेल्डस्पार के रूप में भी जाना जाता है। शिलर नामक ऑप्टिकल प्रभाव और ओरेगॉन सनस्टोन में रंग तांबे के कारण होता है। इस क्रिस्टल के मध्य भाग में बहुत अधिक चमक होती है और आमतौर पर बीच में गहरा रंग होता है और बाहरी भाग होते-होते रंग हल्का हो जाता है। यह दक्षिणी नॉर्वे और संयुक्त राज्य अमेरिका के कुछ इलाकों में पाया गया है। यह ओरेगॉन का आधिकारिक रत्न है। सनस्टोन हाल तक आम नहीं था। पहले सबसे प्रसिद्ध इलाका दक्षिण नॉर्वे में एरेन्डल के पास त्वेडेस्ट्रैंड था, जहां सनस्टोन का द्रव्यमान गनीस के माध्यम से चलने वाली क्वार्ट्ज की नस में एम्बेडेड होता है। ओरेगॉन में बड़े भंडार की खोज के कारण, सनस्टोन अब आसानी से उपलब्ध है। अन्य स्थानों में साइबेरिया में बैकाल झील के पास, और संयुक्त राज्य अमेरिका के कई इलाके, विशेष रूप से मिडलटाउन टाउनशिप, डेलावेयर काउंटी, पेंसिल्वेनिया, लेकव्यू, ओरेगन और स्टेट्सविले, उत्तरी कैरोलिना शामिल हैं।
Astrological View of Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase feldspar / Heliolite)
उपरत्न वर्ग के खनिजपाषाण में काठिन्य, चमक, पारदर्शकता रत्नो की अपेक्षा कम गुणवाले होते है। इनका मूल्य भी कम होता है। अतः इन्हें उपरत्न कहा जाता है। उपरत्नों की संख्या में मतभिन्नता है- आनन्दकन्दकार ने 9 उपरत्न माने है। जबकि आयुर्वेदप्रकाशकार ने 15 उपरत्न माने है। बृहद योगतरंगिणीकार ने 4 ही उपरत्न माने है। रसतरंगिणीकार ने छः उपरत्न माने है। आनन्दकन्दकार ने विमल, सस्यक, कान्त एवं तारकान्त को भी उपरत्न में शामिल कर दिया है। बृहत् योग तरंगिणीकार ने मुक्ता प्रवाल को भी उपरत्न वर्ग में मानकर और भी भ्र्म पैदा किया है। आयुर्वेद प्रकाशकार ने ५ प्रचलित उपरत्नो के अतिरिक्त १० नए उपरत्न को इस वर्ग में शामिल किया है परन्तु सबसे अधिक रस तरंगिणी का मत ही प्रचलित है।

Types of Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase feldspar / Heliolite) as per Astrology
रत्न विज्ञान और आधुनिक रत्न विज्ञान में इसका कोई भेद नहीं मिलता है।
No classification of Suryakant is specified in classics.
Types of Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase feldspar / Heliolite)
Between the solid solution series of two end members i.e. albite (NaAlSi3O8) and anorthite (CaAl2Si2O8), oligoclase feldspar is an important member of the plagioclase feldspar group. This feldspar plays a very important role in petrology, mineralogy, and geology because it has widespread occurrence in metamorphic, sedimentary, and igneous rocks. The different types of feldspar are as follows:
Albite: The oligoclase solid solution series that has a sodium-rich end member is Albite. Its main composition is aluminum, sodium, oxygen, and silicon. Albite has a white appearance and is characterized as colorless to white, translucent to transparent, and vitreous luster in nature. Albite is mainly distributed in syenites, pegmatites, and granites and may be found as a constituent mineral with potassium feldspar, quartz, and mica.
Andesine: A feldspar that exhibits a balance between calcium and sodium and is considered an intermediate composition in the oligoclase solid solution series is Andesine. The chemical formula of andesine is in between anorthite and albite. Andesine is in between opaque to translucent crystals which have a color range of pink, grey, white, and reddish brown. This gemstone is mainly found in the andesite and dacite which are volcanic rocks and crystallize alongside other plagiosides, amphiboles, and pyroxones.
Labradorite: The gemstone which contains a higher proportion of calcium as compared to sodium and is considered as the calcium-rich member of the oligoclase solid end series in labradorite. It has a unique feature that is labradorescence which is the striking iridescence due to which this stone displays vibrant and unique flashes of colors like gold, green, blue, and orange. This stone is mainly distributed in the mafic igneous rocks like gabbaro and basalt and sometimes it also occurs in the metamorphic rocks like amphibolite and gneiss. Labradorite has unique optical properties due to which it is used as jewelry.
Sunstone: The stone that has reflective inclusion and which has a glittering and sparkling effect and which is a member of oligoclase feldspar is Sunstone or Suryakant Mani. Within the crystal structure of the sunstone are goethite and hematite due to which the stone has reflective inclusion. Sunstone is translucent to transparent in color along with this it also exhibits shades of brown, orange-red, and sometimes blue or green. The sunstone is mainly distributed in schist and gneiss which are metamorphic rocks, and it forms in these rocks due to regional metamorphism which occurs under specific geological conditions.
Formation of the Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase feldspar / Heliolite)
The formation of Sunstone / Suryakant is a geological process that occurs in metamorphic rocks under specific conditions that are important for its formation. Sunstone/ Suryakant or Suryamani is primarily oligoclase and is considered a variety of feldspar, which have reflective inclusions that contribute to a sparkling appearance in the sunstone. The combination of geological, environmental factors, and mineralogical processes are the contributors to the formation of the Suryakant. Here’s an overview of the process of the Suryamani formation:
Parent Rock: These parent rocks are often rich in plagioclase feldspar, which undergoes alteration and recrystallization During metamorphism, these parent rocks like gneisses undergo various alteration and recrystallization and are often rich in plagioclase feldspar.
Regional Metamorphism: When continental collision or mountain building collision occurs during tectonic events, the formation of Suryakant occurs due to regional metamorphism which involves high temperature and pressure conditions, which results in changes in texture and mineral composition within existing rocks.
Plagioclase Feldspar Alteration: Aluminum-rich silicates, iron oxides like hematite, goethite, and other various trace elements, present in the mineralogical constituents help in the formation of the characteristic of the Suryakant i.e. reflective inclusions.
Formation of Reflective Inclusions: The distinctive appearance of the Suryakant Upratna is due to the reflective inclusion that is present in it due to the platelets of goethite and hematite. During metamorphism, these platelets align themselves in the structure of the crystal of the feldspar which creates the phenomena that are known as Schiller effect or aventurescence. The Schiller effect is the optical effect that gives a glittering or sparkling appearance to the Suryakant/ sunstone when light reflects off the aligned platelets.
Geological Setting of the Sunstone: Sunstone formation is favored in specific geological settings where regional metamorphism occurs Under appropriate conditions, where regional metamorphism occurs, in specific geological setting Suryakant formation is favored. These geological settings of the Suryakanta/ sunstone include regions with tectonic activity, like areas undergoing orogenic processes associated with mountain-building events or where continental crusts collide.
Weathering and Erosion: The Suryakant stone becomes accessible for collection once it is exposed to the Earth’s surface through various natural processes like weathering, erosion, uplift, etc.
Suryakant/ Sunstone deposits are often found in places where weathering has exposed them to the earth’s surface, like gravel deposits, in association with glacial deposits, riverbeds, etc.
Mining and Extraction: Suryakant mining is done from Sunstone, typically primary or secondary deposits using various techniques that include open-pit mining, dredging, or quarrying. Firstly, miners extract Suryakant/sunstone-bearing rocks from the earth, then those rocks undergo processing that helps to recover the gem-quality material or good-quality Suryakant from them. The sunstone that is extracted from this is then cut, polished, and prepared for use in various things like jewelry, ornamental purposes, astrological purposes, etc.

History of Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase Feldspar / Heliolite)
भारतीय अति प्राचीन काल से सूर्यकांत से भली -भांति परिचित है। भारतीय चिकित्सा के प्राचीनतम ग्रन्थ चरक संहिता में चिकित्सार्थ अनेक स्थलों पर सूर्यकांत का प्रयोग हुआ है। सुश्रुत आदि अन्य परवर्ती संहिताओं में तो और भी अधिक प्रयोग देखने को मिलता है। ८वी शती के बाद रस शास्त्र में इसका शोधन, मारन, गुण, धर्म का विस्तृत विवेचन किया गया है।
Suryakant has a long history. In many places of Charaka Samhita and Sushruta Samhita, the references of Suryakanta have been found where it is used for treatment. With the evolution of Rasa Shastra, the gemstone was extensively used, studied, and described for its therapeutic value.
Characteristics of Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase feldspar / Heliolite)
Suryakant Mani/ Vasu/ Sunstone is a unique semi-precious stone/ Upratna known for its unique characteristics, due to which this Upratna got popularity in jewelry, decorative pieces, and even in astrology. Some key characteristics of sunstone/ Suryakant are as follows:
Chemical composition- Na2O Al2O3. 6SiO2 + CaO7, Al2O3 2SiO2
Color: Suryakant Mani/ Sunstone exhibits a wide range of colors and shades of red, brown, orange, and even green and yellow. These warm colors of sunstone are the result of the presence of goethite platelets and hematite platelets within the matrix of feldspar, which form the characteristic sparkle known as aventurescence.
Aventurescence: The main unique feature of sunstone/ Suryakant mani is its aventurescence, which is also famous as the Schiller effect. This Schiller effect is the optical phenomenon due to which Suryakant exhibits a sparkling or glittering appearance caused by reflective inclusions within the Suryakant semiprecious stone. When light hits the aligned platelets of goethite and hematite of the sunstone, it creates flashes of color and light which gives Suryakant Mani/ sunstone its captivating allure.
Transparency: Sunstone/ Suryakant Mani is mainly Pardarshak i.e. transparent but sometimes also exhibits translucent properties which allow the light to pass through sunstone in various degrees. The quality of the stone, fractures, and interna; inclusions decide the level of Pardarshkta or transparency in sunstone.
Luster: The overall appeal and brilliance of the Suryakant Mani or the sunstone is due to its glassy and vitreous luster. This luster of the Suryakant Mani is due to the reflective inclusion in the sunstone which is due to the direct light.
Hardness: Sunstone/ Suryakant Mani has a hardness ranging from 6 to 6.5 on the Mohs scale, due to which it is suitable for use in jewelry such as rings, earrings, bracelets, and pendants. To prevent scratches and damage Suryakant Mani should be handled with care.
Cut and Shape: Sunstone/ Suryakant Mani is found in various shapes is as rounds, cushions, rectangles, and ovals which shows its unique optical properties. Cabochon cuts of the Suryakant/ sunstone are also famous, especially for sunstone/ Suryakant Mani with strong aventurescence.
Metaphysical Properties: In addition to its physical characteristics, sunstone/ Suryakant Mani is believed to possess metaphysical properties such as increasing creativity, positive energy, and capability. Suryakant mani is often associated with the sun/ Surya Greha and is used in crystal healing practice, enhancing self-confidence and used as the substitute for the Manikya (Ruby) and to nullify the maleficent effect of the sun.
Specific gravity: Suryakant Mani is denser than water as its specific gravity typically ranges from approximately 2.64 to 2.66. This measurement indicates the ratio of the density of the Suryakant Mani to the density of water. The specific gravity or Aapekshit Ghantva of the Suryakant mani may vary slightly depending on the composition and structure of the individual Suryakant mani/ sunstone specimen.
Refractive Index: The refractive index of Suryakant mani/ sunstone typically falls between 1.525 to 1.548, depending on the specific composition and optical characteristics of the Upratna Suryakant Mani. This property of the refractive index of the sunstone affects the way light is reflected and refracted within the semiprecious stone, contributing to the overall brilliance of the Suryakant mani.
Cleavage: Sunstone/ Suryakant mani exhibits two cleavage directions that are distinctive and perpendicular to each other. This means that Sunstone or Suryakant Mani tends to break along these planes when subjected to external forces/ Bahayik Bala. For lapidaries and gem cutters when shaping and faceting the Suryakanta Mani/ Sunstone, understanding the cleavage properties is very important.
In addition to the above-mentioned types of oligoclase feldspar, it also encompasses several other varieties and intermediate compositions along the albite-anorthite solid solution series like oligoclase, anorthoclase, bytownite, and all of them exhibit unique physical and optical properties based on their specific structural arrangements and chemical composition.

यस्तु सुर्यांशु संस्पृष्ट: प्रसुते दहन प्रभावं।
स एक जात्य: कथित: सूर्यकांतम परीक्षके:।।
Clarity, smoothness, evenness, not flaky, becoming clearer on rubbing, and producing fire when kept in the sun are considered the qualities of a good Suryakant/ sunstone. Sunstone is a stone having the shape of a convex lens or magnifying lens which, by keeping in the sun, concentrates the sun rays and produces fire on the other side. Oligoclase is the mineral from which sunstone is produced.
स्पष्टता, चिकनापन, समरूपता, परतदार न होना, रगड़ने पर स्पष्ट हो जाना और धूप में रखने पर आग पैदा करना अच्छे सूर्यकांत/सनस्टोन के गुण माने जाते हैं। सनस्टोन उत्तल लेंस या आवर्धक लेंस की आकृति वाला वह पत्थर है जिसे धूप में रखने से सूर्य की किरणें एकाग्र होकर दूसरी ओर अग्नि उत्पन्न करती हैं। ओलिगोक्लेज़ वह खनिज है जिससे सनस्टोन का उत्पादन होता है।

It is believed by scholars that the following gemstones have effectiveness Diamond life span is 10 years, Ruby/ Manik’s 12 years, Yellow Sapphire/ Pukhraj’s lifespan is 15 years, Blue Sapphire/ Neelam’s life span is 15 years, Emerald/ Panna’s life is 12 years, Coral, Hessonite Garnet and Cat’s Eye’s lifespan is 3 to 5 years, Natural Pearl life span is 12 years.
All the other Uparatnas and other semi-precious alternate gemstones are said to have a lifespan of 3 years.
Over some time, when gemstones i.e. precious and semi-precious stones are worn these gems start to get scratches on their surface, and even start losing their high polishing due to which sun rays stop passing through the gems (Ratna) When these precious gems are wear for a long period a greasy layer starts to deposit on their surface which is probably a mixture of lubricants, oils and other materials that a wearer come in contact with it. As the deposition starts to get thicker with time, it even blocks the rays (different wavelengths) that these stones receive from the planets to give effect. Although gemstones are forever yes their effectiveness for astrological purposes falls and therefore proper and regular maintenance is important.
Therefore, we can consider the life span of semi-precious stone Surya Mani/ Suryopala/ Jwalanopala/ Suryakant Mani/ Vasu (Sun Stone/ Oligoclase feldspar/ Heliolite) to be 3 years.
Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase Feldspar / Heliolite) Used for Different Zodiac Sign (Rashi)
Suryakant is the famous variety of feldspar, which has a radiant appearance and metaphysical properties. As per astrology, the Suryakant is the Upratna used to nullify the bad effects of Surya Greha (sun planet), but it is not tied to any specific zodiac sign (Rashi).
Leo (Sinha Rashi): Singha Rashi is governed by the Surya Greha (sun planet) which gives it warmth, vitality, charisma, and natural leader’s power. Suryakant Mani, with its association with the Surya Greha (sun planet), is believed to be deeply connected with Leo energy, enhancing their natural radiance and helping to shine them even brighter. This vibrant semi-precious stone Suryakant is thought to fill Leos with courage, optimism, and unwavering self-assurance.
Aries (Mesha Rashi): The individuals with Mesha Rashi (Aries zodiac sign) are known for their adventurous spirit, passion, and boldness. Suryakant Upratna energy is believed to increase Mesha Rashi’s dynamic nature, courage, determination, and vitality.
Sagittarius (Dhanu Rashi): The individuals with Dhanu Rashi (Sagittarius zodiac sign) are known for their love of freedom, insatiable curiosity, exploring, etc. Suryakant’s uplifting energy is believed to resonate deeply with Dhanu Rashi’s energy.
Occurrence or Places of Availability of Surya Mani / Suryopala / Jwalanopala / Suryakant Mani / Vasu (Sun Stone / Oligoclase feldspar / Heliolite)
Suryakant/ Suryamani is a unique variety of feldspar, which is famous with the name heliolite and oligoclase feldspar which manifests as a glittering or shimmering effect due to aventurescence. In the region surrounding the town of Tvedestrand Norway, the most quality Suryakant mani/ sunstone is found. Here, Suryakant Mani is extracted from various mines and deposits, which contribute to Norway’s reputation for producing high-quality semi-precious stone Surysakant/ sunstone. Along with Norway, Suryakanta Mani is found in different parts of the world. In India, the Suryakant/ Suryamani is found in the state of Tamil Nadu, which is famous for Suryakant Upratna/ sunstone deposits. The deposits found in India exhibit a wide range of colors from golden to reddish-brown. The Lake Baikal region of Russia is another famous source of Suryakant/ sunstone, which features vibrant shades of red and orange in Upratna Suryakant. Tanzania and the United States, particularly Oregon, also yield Suryakant. The Suryakant/ sunstone found in Oregon is famous for its unique coppery hues. As Suryakant is found in multiple locations worldwide, Norwegian sunstone/ Suryakant mani remains are highly famous for their exceptional quality and captivating color. The geological processes in Norway that occur in the stones are responsible for the exceptional clarity and color of Suryakant making them famous among collectors and jewelry enthusiasts. Whether Suryakant is used in jewelry or astrological purposes or admired in its natural form, it continues to captivate people with its unique beauty.
Sunstone is also available in the Mogok region of Myanmar. The red-colored stone with well-spread golden sparkling dots is called Suryakant mani, according to some classical authors.
सूर्यकांत/सूर्यमणि, फेल्डस्पार की एक अनोखी किस्म है, जो हेलियोलाइट और ऑलिगोक्लेज़ फेल्डस्पार नाम से प्रसिद्ध है, जो एवेन्टुरसेंस के कारण चमकदार या झिलमिलाते प्रभाव के रूप में प्रकट होती है। नॉर्वे के त्वेडेस्ट्रैंड शहर के आसपास के क्षेत्र में सूर्यकांत मणि की सबसे उच्च गुणवत्ता पाई जाती है। यहां, सूर्यकांत मणि को विभिन्न खानों और भंडारों से निकाला जाता है, जो उच्च गुणवत्ता वाले अर्ध-कीमती पत्थर सूर्यकांत/सनस्टोन के उत्पादन के लिए नॉर्वे की प्रतिष्ठा में योगदान देता है। सूर्यकांत मणि नॉर्वे के साथ-साथ विश्व के विभिन्न भागों में पाई जाती है। भारत में, सूर्यकांत/सूर्यमणि तमिलनाडु राज्य में पाया जाता है, जो सूर्यकांत उपरत्न भंडार के लिए प्रसिद्ध है। भारत में पाए जाने वाले निक्षेप सुनहरे से लेकर लाल- भूरे रंग तक रंगों की एक विस्तृत श्रृंखला प्रदर्शित करते हैं। रूस का बैकाल झील क्षेत्र, सूर्यकांत/सनस्टोन का एक और प्रसिद्ध स्रोत है, जिसमें उपरत्न सूर्यकांत में लाल और नारंगी रंग के जीवंत रंग हैं। तंजानिया और संयुक्त राज्य अमेरिका, विशेष रूप से ओरेगन, भी सूर्यकांत का उत्पादन करते हैं। ऑरेगॉन में पाया जाने वाला सूर्यकांत/सनस्टोन अपने अनोखे तांबे जैसे रंग के लिए प्रसिद्ध है। जैसा कि सूर्यकांत दुनिया भर में कई स्थानों पर पाया गया है, नॉर्वेजियन सनस्टोन / सूर्यकांत मणि अवशेष अपनी असाधारण गुणवत्ता और मनोरम रंग के लिए अत्यधिक प्रसिद्ध है। नॉर्वे में पत्थरों में होने वाली भूवैज्ञानिक प्रक्रियाएं असाधारण स्पष्टता और रंग के लिए जिम्मेदार हैं, सूर्यकांत उन्हें संग्राहकों और आभूषण प्रेमियों के बीच प्रसिद्ध बनाते हैं। चाहे सूर्यकांत का उपयोग आभूषणों या ज्योतिषीय प्रयोजनों में किया जाए अथवा इसके प्राकृतिक रूप में इसकी प्रशंसा की जाए, यह अपने अनूठे सौंदर्य से लोगों को मोहित करता रहता है।
