All three are unheated, displaying the trichroic pleochroism tanzanite is known for — brown down one crystal axis, blue on the second, and violet on the third. Heat treatment drives off the brown axis, leaving the blue-violet that defines finished tanzanite, but in rough form all three colors are visible simultaneously depending on viewing angle.\u003cbr\u003eAll three pieces are notably clean for tanzanite rough — good transparency throughout with no significant inclusions visible. Well-sized for yielding finished stones with real presence. A straightforward lot for any cutter who wants to perform the heat treatment themselves and orient for maximum blue or violet in the finished gem. Priced as a lot at $885.​​​​​​​​​​​​​​​​\u003c\/p\u003e\n\u003cp\u003eOrders over $75 get FREE domestic shipping, so it’s easy to fill out your selections without excessive ship costs adding up!!!\u003c\/p\u003e","brand":"SilverHill Lapidary","offers":[{"title":"Default Title","offer_id":42355135676498,"sku":null,"price":885.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/9663\/9570\/files\/4411DE98-E78B-41AF-A92B-1573C77C1F00.jpg?v=1774884119","url":"https:\/\/silverhillrockshop.com\/products\/tanzanite-3pcs-4-43g-facet-rough-parcel-copy","provider":"SilverHill Lapidary","version":"1.0","type":"link"}
