Detect synthetic diamonds with diamond testing instruments

Colorless synthetic diamonds are increasingly being produced. 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. Yet these instruments have not been sufficient for some time now: The colourless moissanite has been on the market since 1998 as an excellent imitation diamond, which also has a 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 takes advantage of the fact that diamonds differ from other colorless stones by 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, colorless synthetic diamonds are increasingly being produced, which these older test devices naturally also identify as diamonds.

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 to differentiate 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 irradiation, the respective diamond types 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.

If you are looking for more free information on the extremely large number of possibilities for diamond determination and would like to receive many technically well-founded examination examples, simply order our whitepaper “Diamond test devices”. This specialist publication was produced in collaboration with Prof. Dr. Jochen Schlueter wrote. He is a qualified mineralogist and is responsible for the permanent collection of the Mineralogical Museum in Hamburg.
