Chatham grows ruby crystals in a six-month process that we’ve refined over decades. We start with a naturally mined seed of fine Burmese ruby. We create the perfect environment rich in chromium to give our crystals a vivid red color. The conditions have to be precisely right: We once lost an entire year’s growth of ruby due to a 0.001% trace of another element in the platinum we use to make our crucibles.
