0.70 ct Blue Sapphire-Montana - Round

At 0.7 carats, this sapphire from Montana carries its blue color through a round cut, measuring 5.1 x 3.5 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. It is heated, a standard and stable treatment that we disclose plainly, the way an honest seller should.

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.
