Hong Kong - based Diamond Search has designed the first system that can detect lab - grown yellow diamonds . By scanning the stones at the temperature of liquid nitrogen , the Diamond Search Device can quickly identify imitation , treated or synthetic diamonds in loose diamonds and those set in jewellery , with no limitation on temperature . “Since this can only be done reliably and safely in a proper laboratory setting, we have chosen not to sell the equipment we develop, but rather to use it exclusively as part of the service we provide the trade. Due to the system 's strict temperature tolerance , the company will not sell the system as a product , but will offer it as a service to the industry .
