PHYSICAL PROPERTIES
The name diamond comes from the Greek 'adamas', meaning 'invincible' in recognition of its exceptional hardness which makes it resist any form of abrasion by other minerals. Diamond is carbon in its pure form. Chemically there is no difference between diamond, coal and graphite. But the unique atomic bonding makes the difference. It has a specific gravity of 3.52, mean Refractive Index is 2.418 and has a hardness of 10 on the Moh's scale.
OCCURRENCE
Diamonds are found in South Africa, Australia, Russia, Kenya, Ghana, Angola, Tanzania, Brazil and India. In India Diamonds are found in Madhya Pradesh, Orrisa and Andhra Pradesh.
IDENTIFICATION
For a Diamond to be real, it must possess some inclusions. These inclusions are visible by naked eye or under magnification. If no inclusions, black spots or milk patches, are visible in a Diamond then either it is a zirconia or piece of glass. Diamonds which do not have any inclusions under 50x magnification are very rare and can be found with collectors only. The small black spots visible in Diamonds are crystals of Graphite or other forms of Carbon. These black spots shine under light. Diamonds have an affinity for grease, the surface of a cut Diamond will generally have a film of grease if it had been handled.
 
The most important test of a diamond is that, all light entering the front of the stone is totally reflected from the back facets which form a series of mirrors. A well cut diamond if viewed from the back and held up to the light, will show only a pinpoint of light from the culet. In addition, looking down on a brilliant-cut diamond one cannot see the wearer's finger below the stone, as can be seen in other stones. White light entering a diamond is dispersed into a spectrum of colours, giving flasks of different colours from the smaller crown facets.
