0.64 ct Yellow Sapphire-Montana - Square

At 0.64 carats, this sapphire from Montana carries its yellow color through a square cut, measuring 4.5 x 3.4 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. The Montana deposits along the Missouri River and Rock Creek give American sapphire its steely blue and teal signature. Its color was brought up by heat, a legitimate and accepted practice that the trade discloses and we disclose here.

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.
