5.13 ct Bi-color Sapphire - Oval

This 5.13-carat sapphire is cut as an oval measuring 11.2 x 9.4 x 6.6 mm, showing a bi-color face, sourced from Madagascar.

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. Madagascar has become a major modern sapphire source, fine material across nearly every color at more reachable prices than the classic localities. It is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

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.
