When set in a jewel, the color in these stones is often masked by the color of the surrounding precious metal. These diamonds are wonderful additions to any gemstone collection and striking center stones when set in a custom designed jewel. However, these diamonds are truly striking and worth acquiring, if they are within your budget. The great value of fancy colored diamonds has enticed many modern-day alchemists to try to recreate these rare and beautiful gems in their laboratories. As scientific knowledge of the causes of natural fancy colored diamonds increases, the efforts to create synthetic and treated colored diamonds become more successful.
Synthetic diamonds are artificial diamonds that have been created in a laboratory.
By varying the heat and pressure during formation, adding foreign elements, and irradiating the finished crystals, synthetic diamonds can be made to imitate natural colored stones. There is currently a wide spectrum of synthetic colored diamonds available. Treated diamonds are natural diamonds that started out with an unappealing or slightly off color. By exposing these less desirable stones to the same high-tech alchemy used to create synthetic colored diamonds, the color and appearance of these diamonds can be materially improved. Recently we have seen treated diamonds with vibrant yellowish green, red and blue colors enter the market.
