Rare Diamonds

Did you know that colored diamonds are known in the jewelry world as “fancy colored diamonds”… rarer and more expensive than their white counterparts.

The conditions are rare in which these colored diamonds are made.  It is said that for everything 10,000 colorless diamonds there is one natural colored diamond to be mined… It is this entirely natural process of geographical formation which ensures that each natural color diamond, like these from our Masterwork Collection is one of a kind.

How do these uniquely colored diamonds form? Well it depends on pressure, and natural elements in the atmosphere.

* For a yellow diamonds like these to form, nitrogen must be present during heat and pressurization.

Other fancy colored diamond colors are formed by different circumstances:

- Blue diamonds form when boron is present and reacts with carbon molecules.
- The presence of hydrogen will impact a diamond to become a violet hue.
- Pink and red diamonds form when there is an abnormal amount of molecular compression during the diamond’s formation.
- Natural radiation over the years will give a green hue to a diamond.
- Brown diamonds also form when intense compression is present.
- The black diamond is probably the rarest of them all. A black diamond is not a single crystal it is made up of millions of tiny crystals bonded together. Microscopic deposits of sulfides between these bonds are responsible for the dark color.
