Diamonds Information by Mario Basso
History has proven that diamonds are revered for having an irresistible and tempting power all of its own. A reputation that has been built on its brilliance, its resilience and the fact that it is the valuable, rarest and most desirable of all gems.
A brilliant cut Diamond depends largely on the quality of the cut And Diamonds of great proportion show illuminating reflections of light whereas diamonds which are cut too deep let light escape. The sheer radiance of any diamond is largely determined by the amount of white light reflected from the gem.
