Ruby is a member of the corundum mineral family, which also includes sapphire. It is the most valuable of the corundum gems, and the finest rubies can even surpass the price of diamonds. It’s no wonder that, in ancient Sanskrit, ruby was called ratnaraj: the king of precious stones. Due to its vivid red color, ruby is associated with matters of the heart.
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. Chromium is the trace element that causes ruby's red color.
In Sanskrit, ruby is ratnaraj, meaning the king of gems.
