Red Natural Diamond

Green colors are the hottest for the human brain to process and for the human eye to see.

The green color in natural diamonds is caused by natural radiation of the earth and probably uranium ore. Since radiation is the cause of color in both cases of natural and enhanced diamonds it poses an identification nightmare. Brown or green radiations stains on the surface usually indicate a natural green color.

A natural fancy intense green diamond can wholesale over a $100,000 a carat and a treated green is practically worthless.

Natural green diamonds remain very strong in price. These stones are so rare they are in few hands. A carat size fancy green can wholesale for $60,000 to $125,000 a carat. A carat size fancy intense green can wholesale from $125,000 to a $150,000 a carat.

Naturally, the green color appears when the diamond crystal comes into contact with some radioactivity, and the irradiation discolors the stone, causing a green stain.

Natural red diamonds are so rare that most jewelers have never seen one, and will never own one. In recent years, methods of producing intensely colored diamonds, probably including fancy red, have been developed, although we have never yet seen any red diamond natural or treated. We believe that the process probably recreates the conditions which existed millions of years ago to produce natural fancy colored stones. The treatment can only work with a small minority of diamonds, and involves irradiating them causing the color change, usually followed by heat treatment to stabilize the color.

How expensive is a Red Diamond?

Quality for quality, fancy red diamonds are more expensive than ordinary near-colorless ones. The processing adds to the costs, so it is generally only worth treating diamonds of high clarity. The diamonds selected for treatment usually start off a one of the less desirable colors such as brown or yellow. There is no certainty about the final color that any particular stone will be after treatment.
