0.66 ct Blue Sapphire - Round

This 0.66-carat sapphire is cut as a round measuring 5.6 x 3 mm, with a blue body color, sourced from Thailand.

Sapphire is the gem form of corundum, second only to diamond in hardness among the classic gemstones, which is why it wears so well in jewelry worn daily. Thailand is both a corundum source and the great cutting and finishing hub of the colored gemstone trade. 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.
