CVD diamonds can pass a diamond tester due to their high thermal conductivity, which is similar to natural diamonds. However, specialized testing and equipment are required to differentiate between CVD diamonds and natural diamonds accurately.
CVD diamonds are created through a process called chemical vapor deposition, which results in a diamond that is pure on the inside. They share many physical properties with natural diamonds, including high thermal conductivity. This property allows CVD diamonds to pass standard diamond testers, which primarily measure thermal conductivity to distinguish diamonds from other materials like cubic zirconia or glass.
However, while CVD diamonds can pass a basic diamond tester, they can be distinguished from natural diamonds through more advanced testing. For instance, CVD diamonds may exhibit "strain lines" or unique fluorescence under UV light, which are not typically seen in natural diamonds. These characteristics are not visible to the naked eye and require specialized equipment or a loupe to observe.
Furthermore, the diamond's grading report can indicate whether the diamond was grown through CVD or another method. The GIA (Gemological Institute of America) and the IGI (International Gemological Institute) are two authorities that can accurately test and identify CVD diamonds. They use specialized equipment to detect minute trace elements and other characteristics specific to CVD diamonds.
In summary, while a basic diamond tester can confirm that a stone is a diamond (natural or CVD), it cannot differentiate between them. To accurately identify a CVD diamond, one must rely on the expertise of gemological laboratories like GIA or IGI, which have the necessary equipment and knowledge to perform detailed analyses.
