Colorless synthetic diamonds are being produced more and more frequently. Diamond testing instruments can help to separate real diamonds from imitation or synthetic diamonds. In the past, diamond testers only detected the properties of the different thermal conductivities of stones, thus distinguishing real diamonds from other natural stones and imitations. For some time now, however, these conventional devices have no longer been sufficient: With the colorless moissanite, an excellent diamond imitation has been on the market since 1998, which also has very good thermal conductivity.
With our modern test devices, many more properties can be determined today: some measure thermal and electrical conductivity in parallel, others detect UV transmission. The device function makes use of the fact that diamonds differ from other colorless stones due to their special thermal, electrical and optical properties.

WORKING WITH IMPROVED DIAMOND TESTING INSTRUMENTS
Test devices that were developed in earlier years and only measure the thermal conductivity of stones cannot, as of today, make any clear conclusions about diamonds. At the same time, more and more colorless synthetic diamonds are being produced, which are of course also identified as diamonds by these older testing devices.
For this reason, new devices have been developed. This generation of test instruments simultaneously checks the electrical and thermal properties of the stones. Moissanite, for example, is a good electrical conductor and can therefore be distinguished from diamonds.
Test devices such as the SmartPro Screen I help distinguish between natural and colorless synthetic diamonds based on UV transmittance. Synthetic diamonds have a different transmittance or absorption than natural diamonds. When exposed to UV radiation, the different types of diamond absorb different amounts of UV light. Testing instruments such as the SmartPro Screen I help to distinguish between colourless natural and synthetic diamonds based on UV transmittance. The differences of the UV absorption of these stones are significant enough to differentiate.
