Yes, every shade of brown that you can imagine is available in the different colours of brown diamonds, including chocolate.
No, they are diamonds. They are called chocolate diamonds because of their brown color.
Faceted, finished brown diamonds are simply diamonds within that colour range. Chocolate diamonds are an intense brown colour.
Chocolate, or brown, diamonds are made just like any other diamonds, when carbon is placed under extreme pressure. The brown color comes, in most cases of natural diamonds, seems to come from distortions or defects in the crystal matrix. In synthetic diamonds, the brown color results from the presence of nickel and nitrogen atoms in the crystal matrix. Brown diamonds are the most common colour of diamonds found. 'Chocolate' is the name of one shade of this brown colour. All diamonds are formed naturally far below the surface of the earth and erupted to the earth's surface through volcanic pipes.
'Chocolate diamonds' are named thus because this shade of brown diamond is the colour of chocolate. Some brown diamonds are natural diamonds; some brown diamonds are manufactured diamonds. A gemologist will help you determine the source of your brown diamond. Manufactured diamonds are always less expensive than natural diamonds with similar characteristics.
Brown diamonds are not rare, but diamonds are rare.
Naturally occurring chocolate diamonds (also known as brown diamonds) can are formed deep inside the earth and get the brown color due to irradiation treatment, nickel impurities and lattice defects associated with plastic deformation.
'Regular diamonds' are diamonds described without colour. 'Chocolate diamonds' are brown diamonds that include a description of the colour.
Brown diamonds are the most common of coloured diamonds found. Chocolate is simply the name of one of the shades of natural brown diamonds. Lab-created diamonds are generally 'white' diamonds.
'Chocolate diamonds' is a trade name for brown diamonds. Brown diamonds are the most common colour of gem-quality diamonds found everywhere on earth except Europe and Antarctica.
'They' in this case, is Mother Nature. From WiseGeek: "Most chocolate diamonds come from diamond mines in Australia. The natural occurring brown color is thought to be created by the earth's pressure on the diamonds deep in the earth." Chocolate diamonds earn their colour by virtue of the stone's plastic deformation.
Chocolate is one name used to describe brown diamonds, the most common colour of diamond found. From its Wikipedia entry for natural brown diamonds: "Whereas the brown color due to irradiation or nickel impurity can be easily recognized through spectroscopic (e.g. absorption) measurements, the majority of natural brown diamonds do not show any characteristic absorption peaks. Whereas the consensus has been reached that the color relates to the plastic deformation, the particular reason has been reliably identified (large clusters of vacancies) only in type IIa natural brown diamond."
A "chocolate diamond" is the name of one color of brown diamond, with color ranges from cognac to honey to champagne and shades in-between.A "chocolate diamond" is actually one of many types of colored diamonds. Other colored diamonds, also called "fancy diamonds," include pink, yellow, blue, green, purple, black, red and orange.Although colored diamonds were once considered undesirable, they have become very popular amongst those looking for an alternative to conventional white diamonds.History of the nicknameSome colored diamonds gained commercial names over the years, thus having multiple names which actually mean (more or less) the same thing.In this case, a New York firm, Le Vian, coined the trademark of Chocolate Diamonds(R) in 2000 to refer to its brand of natural fancy color brown diamonds. In 2008 the trademark was granted federal registration.
