3.66 ct Blue Tanzanite - Oval

This 3.66-carat tanzanite is cut as an oval measuring 11 x 7.9 x 6.3 mm, with a blue body color, sourced from Tanzania.

Tanzanite is the blue-violet zoisite found in exactly one place on earth, a few square kilometers of hills in northern Tanzania. Tanzania holds some of the most interesting modern gem deposits, including several found nowhere else. It is heat-treated, a common and honest preparation across the colored-stone trade, disclosed on every listing.

One of a kind, it exists exactly once; there is no second example to size up or down. It is the rarer object, and the kind of gemstone that becomes an heirloom. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
