Ruby is distinguished for its bright red color, being the most famed and fabled red gemstone. Beside for its bright color, it is a most desirable gem due to its hardness, durability, luster, and rarity. Transparent rubies of large sizes are even rarer than Diamond s. Ruby is the red variety of the mineral Corundum. Rubies can command the highest per-carat price of any colored stone. This makes ruby one of the most important gems in the colored stone market. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color.

This is done by heating them in molten lead glass which has a very similar refractive index to Ruby gemstones. Fracture-filled Rubies are significantly cheaper than their more authentic counterparts, and because of this one should always buy Ruby from a reputable dealer.
The center of Ruby gemstone trade is in Bangkok, Thailand. The Chantaburi Province in Thailand has always been an important source of Rubies, producing gems with excellent clarity but with less desirable browner tones.
However, the color of Thai Rubies are able to be improved by heat treatment. The Thai Ruby deposits were exhausted in the 's. The most valuable Rubies with the finest natural color come from Mogok, Burma Myanmar.
There are strict trade embargoes and restrictions again Burma for its human rights violations, and several countries, especially the United States, ban any exports from this county.
The Ruby mines of Mogok have been under the tight control of the Junta government; however, a new very significant Ruby source was discovered in Burma in in Mong Hsu.
The color of these Rubies aren't as good as Mogok, but they too can be improved through heat treatment. In , new Ruby sources were discovered in Madagascar in Vatomandry and Andilamena.
These deposits turned out to be very extensive and productive, and Madagascar is now one of the leaders in Ruby output.

Ruby and Spinel often occur together in the same mineral environment and localities. The most famous ruby, the Black Prince's Ruby, set into the royal crown of England, was once thought to be the largest cut Ruby, until scientific analysis determined it to be in fact Spinel.
Garnet particularly Pyrope and red Tourmaline Rubellite may also resemble Ruby, though Ruby is significantly harder. Have a question about Ruby?
