0.64 ct Bi-color Sapphire - Round

This 0.64-carat sapphire is cut as a round measuring 5.5 x 3.2 mm, showing a bi-color face, sourced from Sri Lanka.

Sapphire is corundum, one of the hardest materials in the gem world after diamond, and it comes in every color the species holds except the red the trade reserves for ruby. Sri Lanka's gravels are read by miners whose skill is generational, and a stone that reaches the cutter has already beaten long odds. It is heated, a standard and stable treatment that we disclose plainly, the way an honest seller should.

This is a center-stone-grade gemstone with a character of its own, chosen rather than settled for. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
