Tanzanite was reportedly first found there in 1968, and the deposit is subdivided into Blocks A, B, C, and D, with Block D worked by many small pits. For collectors, the locality is especially important for tanzanite and has also produced notable mineral associations including tremolite, tsavorite, prehnite, axinite-(Mn), kyanite, and merelaniite.\u003c\/p\u003e","brand":"Crystal Castle","offers":[{"title":"Default Title","offer_id":49463482744987,"sku":null,"price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3012\/6217\/files\/e9ab081b-d371-4c67-a222-b8b9560212be.jpg?v=1788728594","url":"https:\/\/www.overtonfamilyjewels.com\/products\/auction-win-61c12abb-42f6-4c59-9e20-f59056a44fb2","provider":"OFJ's Crystal Castle","version":"1.0","type":"link"}
