The origin of the word ruby comes from the Latin word « rubeus » becaue of its color. Until the XIX century, the red spinel and garnet were often confused with rubies. Some gems present in royal jewels that were believed to be rubies and symbolized power and royalty turned out to be red spinels.
A rub is considered one of the rarest gems due to the rarity of the mine deposits. It is therefore the most expensive gemstone after diamonds. Burma (Myanmar) produces the most beautiful gemstones that are called « Pigeon’s Blood » (pure red with a blue tint) and when a ruby is over 3 carats, it generally exceeds the price of a diamond of the same quaity and equivalent weight.

The ruby’s cut is almost as importnt as its clarity. A well cut ruby will increase its value and the ruby will be more brilliant. Many cuts exist for rubies but gemologists consider that the oval cut, the pear and cushion cut are the most beautiful to enhance the color of the ruby. The round shape can also give the gem a nice brilliance but this shape is difficult to find in a weight over 3 carats.
