1.36 ct Red Ruby - Cushion

At 1.36 carats, this ruby from Sri Lanka carries its red color through a cushion cut, measuring 6.5 x 5.6 x 4.2 mm.

Ruby is the red form of corundum, sapphire's sibling species, and fine examples are among the most valuable colored gemstones per carat. Its color was brought up by heat, a legitimate and accepted practice that the trade discloses and we disclose here. It is GIA-certified, and the report is available to view.

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.
