    Diamond Gems

    So brilliant, they were once thought to be fallen stars, diamonds are the most sought-after gems on earth. Potent symbols of love, devotion, pride, wealth, and power, diamonds mean forever. Chatham lab-grown diamonds can’t be distinguished from mined diamonds except with sophisticated gemological equipment.

    Chatham Lab-Grown Diamonds
    Chatham Lab-Grown Diamonds

    Like diamond itself, growing these brilliant crystals is extremely hard. Despite the difficulty and effort required, lab-grown diamonds sell for less than mined gems of the same quality. Depending on size and weight, you could save thousands of dollars by choosing a lab-grown diamond.

    Remember, lab-grown diamonds are 100% diamond. The only difference between lab-grown diamonds and mined diamonds is where they form: in the earth or in the lab. Chatham lab-grown diamonds can’t be distinguished from mined diamonds except with sophisticated gemological equipment.

    About Diamonds
    About Diamonds
    Diamond is a girl’s best friend. Named from the Greek adamas, which means unconquerable, diamond is the hardest material on earth. In 1477, Mary of Burgundy received the first recorded diamond engagement ring. Today, most couples promise to marry with this beautiful gem.
