Which tretment can remove some or all color form certain types of light brown diamonds?

There is apparently a high-pressure, high heat process that can alter a brown diamond's colour. This treatment can 'heal' lattice defects that cause the brown colour. Note, however, that treated diamonds are less valuable that natural diamonds. A GIA certified gemologist will always be able to tell that a diamond has been treated.


How are brown diamonds produced?

Brown diamonds are the most common color of diamonds found in the gem-quality category. There are several theories as to why diamonds are coloured brown. According to its Wikipedia entry:"Several causes have been identified, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation; the latter is considered as the predominant cause, especially in pure diamonds."


Where are brown diamonds mined?

Australia produces brown diamonds from their mines.


How is a chocolate diamond created?

Chocolate diamonds are natural diamonds with a brown color caused by the presence of nitrogen impurities. The intense brown color is enhanced through heat treatments, which further intensify the color and improve the diamond's appearance. These treated brown diamonds are marketed as "chocolate diamonds" for their unique color.


What makes diamonds chocolate?

How do they make chocolate diamonds?

Chocolate diamonds are not made in a traditional sense like lab-grown diamonds. They are natural brown diamonds that undergo a specific treatment process to enhance their color, making them suitable for use in jewelry. This process involves high-pressure, high-temperature treatments to alter the diamond's color from a pale brown to a rich chocolate hue.


Are chocolate diamonds natural or manufactured?

'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.


What metals do diamonds have in them?

Diamonds are formed from carbon. Some brown diamonds may contain trace amounts of nickel -- otherwise diamonds do not contain metals.


What are brown diamonds?

Brown diamonds are the most common colour of diamonds mined, of gem-quality. Only about 20% of all diamonds mined are of gem quality.


What do chocolate diamonds look like?

Faceted, finished brown diamonds are simply diamonds within that colour range. Chocolate diamonds are an intense brown colour.


Is chocolate diamonds man made?

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.


Are chocolate diamonds the same as regular diamonds?

No, chocolate diamonds are a marketing term used by Le Vian to describe brown diamonds. They are still real diamonds but have a distinct brown color due to the presence of nitrogen impurities. Regular diamonds can come in a variety of colors but are most commonly white or colorless.
