About Ruby Stone / Manik Stone

Ruby is the red to pinkish red variety of the Corundum mineral group that also includes Sapphire which is known primarily as the blue variety although it is available in many colors. Ruby is one of the top four gems (Diamond, Sapphire, Ruby and Emerald) in popularity. This is mostly due to its beauty, intense color and toughness in jewelry. With a Moh’s hardness of 9.0 and no cleavage, it is a very durable gem for jewelry. Ruby’s red color is caused by minor amounts of trivalent Chromium (Cr) replacing Aluminum (Al) in the crystal structure. Pure Cr2O3 occurs in nature as the mineral Eskolaite, which is green.

Ruby is available from many locations around the world. Some of these locations such as Burma, Ceylon and Madagascar, are well known for their fine Rubies. Ruby is also known as manickam stone in Tamil.
