0.30 ct Red Ruby - Round

At 0.3 carats, this ruby from Burma carries its red color through a round cut, measuring 4.2 x 2.4 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 entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
