Purple
Purple diamonds are very rare. It is believed that they have a similar cause of color as pink diamonds; crystal distortion. They are most often found in Siberia and are generally small in size. There are no historical or famous purple diamonds. This may be due to their inhospitable location. Purple diamonds larger than 5 carats are extremely rare, and their color rarely reaches the intense and vivid color grades.
White
Natural color white diamonds are not colorless, but are actually white. This can often cause confusion as the term is used loosely. A pure white diamond has a translucency or even opacity that makes the diamond white. This is often caused by sub-microscopic inclusions. They occasionally exhibit a weak play of color (similar to opals) called opalescence. These are highly prized among conniseurs.
Chameleon
Chameleon diamonds are often confused with green diamonds, but they populate a different and discrete area of color space. Their color is a combination of yellow and green sometimes also a bit of brown or gray. They often come with three colors to describe them such as grayish greenish Yellow. and while this does accurately describe the color olive is a simpler, more concise term. They can range is size from small to large (some are 10+ carats). Occasionally they exhibit a color change when heated or left in the dark, these are known as chameleon diamonds.
