0.90 ct Blue Sapphire - Round

This 0.9-carat sapphire is cut as a round measuring 5.7 x 3.8 mm, with a blue body color, 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. Its color was brought up by heat, a legitimate and accepted practice that the trade discloses and we disclose here.

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 photographs it in good light, to give you the truest look a screen can.
