Prominent lengthwise striations extend across the broad, bladed crystal surfaces, creating a subtle silky sheen. Warm golden-brown mineral staining and remnants of associated matrix accentuate the crystal's natural structure, while its layered growth and contrasting blue tones give the specimen striking visual depth.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eKyanite is an aluminum silicate mineral recognized for its distinctive bladed crystal habit and unusual directional hardness, which varies depending on the crystallographic orientation. It commonly forms in aluminum-rich metamorphic rocks subjected to elevated pressures. The Sultan Hamud area of Kenya is known for its kyanite occurrences, making this vintage-labeled specimen an appealing example of East African mineralogy and classic metamorphic mineral formation.\u003c\/span\u003e\u003c\/p\u003e","brand":"The Crystalary","offers":[{"title":"Default Title","offer_id":67782231883907,"sku":"barrydwr9-2of2-220","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0390\/4634\/8931\/files\/IMG_3103.jpg?v=1791933538","url":"https:\/\/www.thecrystalary.com\/products\/arfvedsonite-barkevikite-variety-near-hernandez-california-usa-copy","provider":"The Crystalary","version":"1.0","type":"link"}
