1.18 ct Red Ruby - Cushion

At 1.18 carats, this ruby from Burma carries its red color through a cushion cut, measuring 6.4 x 5.2 x 3.7 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 carries no treatment of any kind, so the color you see is the color that came out of the ground. It is GIA-certified, and the report is available to view.
