0.59 ct Blue Sapphire - Square

This 0.59-carat sapphire is cut as a square measuring 3.6 x 2.6 mm, with a blue body color, sourced from Sri Lanka.

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. 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 wholly untreated, its color finished by geology rather than by any furnace or enhancement.

Its exact combination of color, cut, and origin is its own, the kind of center stone you choose on purpose and build a piece around. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
