Purple Diamond

Purple diamonds are coloured by minute graining within the diamond structure. The resulting shades vary from pale orchid to deep imperial purple. As purple is a colour intermediate between red and blue it can display both warmth and cool effects. Although pure purple diamonds are very hard to come by, many are available with a grey or pinkish modifier, and other coloured diamonds can display a purplish secondary hue. Most natural purple diamonds tend to be small, generally weighing 2 carats or less.
Please note that a significant amount of treated diamonds exist on the market. The purpose of the treatment is to increase the colour.
