The natural color and relative durability make it an appealing option for all types of jewelry designs.\u003cbr\u003e\u003cbr\u003eIolite is the gem name for cordierite, a silicate of aluminum and magnesium. Its name comes from the Greek word “ios,” meaning violet. Similar to tanzanite in color, but more affordable, this stone gets its color primarily from iron. Most iolite is found in gravel beds in the form of water-worn pebbles.\u003cbr\u003e\u003cbr\u003eDue to pleochroism or dichroism phenomena, iolite displays different colors when viewed from different angles. Iolite can appear almost clear in one orientation, and then present a deep purple color in another orientation. Because iolite typically has very few inclusions, it is ideal for faceting and displays a clear, bright color.\u003cbr\u003eThese are AGTA-grade gemstones.\u003cbr\u003e\u003cbr\u003eSpecifications \u0026amp; Features\u003cbr\u003eAttributes\u003cbr\u003eMaterial: Iolite\u003cbr\u003eStone Shape: Round\u003cbr\u003eStone Size: 8mm\u003cbr\u003eStone Type: Natural\u003cbr\u003eColor: Violet-blue\u003cbr\u003eEnhancement: None (N)\u003cbr\u003eMohs Hardness: 7–7.5\u003cbr\u003eRefractive Index: 1.53–1.55\u003cbr\u003eSpecific Gravity: 2.58–2.74\u003cbr\u003eMineral Source: INDIA \u003cbr\u003eListed with ExportYourStore.com","brand":"Sea Star Trading","offers":[{"title":"4mm \/ Agta Grade","offer_id":52015733702972,"sku":"65516_4mmAgtaGrade_C431B","price":8.45,"currency_code":"USD","in_stock":true},{"title":"5mm \/ Agta Grade","offer_id":52015733768508,"sku":"65516_5mmAgtaGrade_5CC6D","price":18.52,"currency_code":"USD","in_stock":true},{"title":"6mm \/ Agta Grade","offer_id":52015733801276,"sku":"65516_6mmAgtaGrade_C93C4","price":37.03,"currency_code":"USD","in_stock":true},{"title":"8mm \/ Agta Grade","offer_id":52015733834044,"sku":"65516_8mmAgtaGrade_C63D5","price":99.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/6964\/9468\/files\/il_fullxfull.5018873598_3uw0.jpg?v=1759851015","url":"https:\/\/www.seastarstrading.com\/products\/iolite-round-cabochon-choose-your-size","provider":"Sea Star Trading","version":"1.0","type":"link"}
