3.51 ct Blue Tanzanite - Oval

At 3.51 carats, this tanzanite from Tanzania carries its blue color through an oval cut, measuring 11.2 x 7.9 x 5.5 mm.

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 heated, a standard and stable treatment that we disclose plainly, the way an honest seller should.

A single natural gemstone with no duplicate behind it; once it is set or collected, there is no other. It will outlast everyone who owns it, which is most of what an heirloom really is. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
