Evoking blood and fire, the ruby is synonymous with courage, bravery and victory.
The ruby owes its name to its red color, from the Latin “rubeus” meaning “reddish”.
This gem is one of four gemstones along with diamond, emerald, and sapphire.
It was only around 1800 that it was attached to the corundum group with sapphire, before this date ruby, red spinel and pyrope garnet were called “carbuncles”.
The color of ruby corundum, often unevenly distributed in streaks or spots, is attributed to the presence of chromium oxide, with a participation of iron for the brown tones.

The color and nature of the inclusions of the corundum ruby give an indication of its geographical origin.
The most sought after of all the colors of corundum ruby is the so-called “pigeon’s blood” pure red with a hint of blue, often of Burmese origin in the Mogok region of Burma renamed Myanmar in 2010.
