    • n ruby The clear rich-red variety of corundum. (See corundum.) It is highly prized as a gem, and ranks even above the diamond, fine examples of from one to five carats selling at a price from three to ten times greater than that of a diamond of corresponding size and quality. The finest rubies, those of a pigeon's-blood color, are found in Upper Burma, near Mogok, north of Mandalay; they occur there in place in a crystalline limestone, also in gem-bearing gravels; the spinel ruby is a common associate. Rubies of a dark-red color, sometimes with a tinge of brown, are found in the region about Chantibun, Siam; others, of a dark-pink or purplish tint, in Ceylon. A magenta-colored ruby from Victoria, in Australia, is locally known as barklyite. In Great Britain rubies of a dark-red or beef's-blood color are highly prized.

The pale-red topaz from Brazil is also sometimes called Brazilian ruby, and a red variety of garnet, rock-ruby.
