1.66 ct Red Ruby - Pear

At 1.66 carats, this ruby from Burma carries its red color through a pear cut, measuring 7.1 x 5.2 x 3.1 mm.

Ruby is the red form of corundum, sapphire's sibling species, and fine examples are among the most valuable colored gemstones per carat. Burma is the historic benchmark for ruby; Mogok reds are what the trade grades against, from deposits narrow enough to keep the name expensive. It is heated, a standard and stable treatment that we disclose plainly, the way an honest seller should.

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.
