1.60 ct Bi-color Sapphire - Round

At 1.6 carats, this sapphire from Thailand carries its bi-color face through a round cut, measuring 5.3 x 3.8 mm.

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 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. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
