0.51 ct Green Sapphire - Round

At 0.51 carats, this sapphire from Thailand carries its green color through a round cut, measuring 4.9 x 3.1 mm.

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. 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.

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 filmed by Caveman Gems in good light, shown as honestly as a screen allows.
