Comment: Remarkable color play from an unheated blue tanzanite (and green-purple zoisite). While the classic blue of Tanzanite is the result of heat treatment, this stone has NOT been treated. It comes with a rare AGL prestige report stating 'no evidence of heat' (see report under 'more images'). Perhaps the only blue tanzanite with this esteemed distinction available. A trophy for the collector of the rarest untreated gemstones. Set in a pendant this beauty will not cease to charm, not ever. Tanzanite blue, electric green, cornflower, violet, lavender purple and all in-between. No visible inclusions even under the lens. To see it, is to love it.
