To address this need, the SDC-100 and SDC-200 diamond testers have been developed using modern intelligent technology, incorporating years of gemological research and identification data. These instruments provide a fast, non-destructive solution for distinguishing between natural diamonds, CVD/HPHT lab-grown diamonds, and moissanites. The SDC-100 diamond tester is designed to analyze loose diamonds ranging from 2mm to 10mm, while the SDC-200 offers the same capabilities but can also test mounted diamonds. Based on established testing principles, these gemstone identification instruments offer a practical and efficient approach for professionals handling diamond authentication.

Note: These gemological instruments are intended exclusively for testing natural diamonds, CVD/HPHT synthetic diamonds, and moissanites. They cannot be used to analyze other types of gemstones.

Features

Notes

• Not suitable for distinguishing natural colored diamonds, only applicable for Cape series (colorless) diamonds.
• Before using the SDC-100 diamond tester, it is recommended to first sort out moissanites, synthetic diamonds (CVD/HPHT), and natural diamonds from the batch diamonds with a thermal conductivity tester.
• If the test result indicates CVD/HPHT, there is a small possibility that the stone could be a natural diamond (such as Type IIa Diamond). Further testing is advised.
