1.37 ct Blue Sapphire - Cushion

At 1.37 carats, this sapphire from Madagascar carries its blue color through a cushion cut, measuring 6.9 x 5.7 x 4.5 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. Madagascar has become a major modern sapphire source, fine material across nearly every color at more reachable prices than the classic localities. Its color was brought up by heat, a legitimate and accepted practice that the trade discloses and we disclose here.

A single natural gemstone with no duplicate behind it; once it is set or collected, there is no other. It will outlast everyone who owns it, which is most of what an heirloom really is. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
