0.73 ct Blue Sapphire - Round

At 0.73 carats, this sapphire from Thailand carries its blue color through a round cut, measuring 5.7 x 3.2 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 heated, a standard and stable treatment that we disclose plainly, the way an honest seller should.

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