Diamond, the birthstone for April

Colours
When thinking of Diamonds you immediately tend to picture a sparkling translucent stone that twinkles in the light. This is generally the case although more rare Diamonds do come in a variety of ‘fancy’ colours. They can be found naturally in such colours as pink, blue, yellow, green and orange. but are extreemly rare. ‘Chocolate’ Diamonds are also naturally found and are becoming more popular.
Treated Diamonds, which exhibit the colours of the rare ‘fancy’ colours, are also available. It worth noting that there has been some problems in the past with the treated pink Diamonds and their colour stability.

Physical Properties
Measuring 10 on the Mohs scale, Diamond is not only the hardest gemstone it is also one of the hardest substances known to man. In fact Diamonds are so hard that when they are cut for jewellery other Diamonds have to be used to grind the facets.
