There are over 300 shades of colour that natural diamonds come in including pink, black, red and yellow. This is because of mineral impurities and lattice defects in the diamond.
Natural blue diamonds represent one colour of natural diamonds -- others being yellow, orange, green, pink and so forth. Blue diamonds contain boron within their chemical structure, which gives the stone reflective properties that make it appear blue.
Althoguh clarity or color enhanced diamonds are "safe" to buy, they should be dramatically discounted from the price of natural diamonds.
'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.
There are four main types of diamonds based on their color and origin: natural diamonds, synthetic (or lab-created) diamonds, fancy color diamonds, and industrial diamonds. Natural diamonds form over billions of years under high-pressure conditions in the Earth’s mantle, while synthetic diamonds are created in laboratories using similar processes. Fancy color diamonds are graded based on their hue, saturation, and tone, while industrial diamonds are used for cutting and grinding rather than for jewelry. Each type has unique properties and applications.
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.
No, chocolate diamonds are not made out of chocolate. They are a marketing term used to describe brown diamonds that have a rich, deep color resembling that of chocolate. These diamonds are natural diamonds that have not been treated or altered to achieve their brown hue.
Natural diamonds can be industrial diamonds or gemstone quality diamonds. Gemstone quality diamonds are worth more than industrial diamonds. If by 'industrial', you mean man-made, then a natural diamond will always be more valuable than a man-made diamond of equal carat weight, unless the natural diamond is not of gemstone quality.
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.
Natural diamonds are not blue in color. Blue diamonds are formed when the presence of boron impurities during their formation process causes them to absorb certain wavelengths of light, resulting in a blue hue.
No, chocolate diamonds are not man-made. They are a natural variety of diamond that get their distinct brown color from the presence of nitrogen during their formation process. They are also known as champagne or cognac diamonds.
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."
