0.65 ct Blue Sapphire - Round

This 0.65-carat sapphire is cut as a round measuring 5.1 x 3.4 mm, with a blue body color, 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 entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
