DiamondPlus | Model# .

The DiamondPLus is a compact screening device intended for use in all locations where polished diamonds are handled. Its primary purpose is to screen for type II high-pressure-high-temperature (HPHT) treated natural diamonds. It can also separate out some synthetic categories and will refer all irradiated diamonds. With the sample immersed in liquid-nitrogen, the instrument makes a laser-excited photoluminescence measurement. It is therefore is only suitable for testing loose diamonds between 0.05 and 10 carats. Within 15 seconds, DiamondPLus returns an automated 'PASS' or 'REFER' result. Please note, diamonds that are referred by the instrument should not be classified as HPHT treated or synthetic without additional testing. In addition to referring all HPHT treated type-II diamonds, the instrument will also refer a percentage of untreated natural type-II diamonds. Testing on ALL referred diamonds should be carried out using more sensitive, laboratory-based, low-temperature photoluminescence equipment. From these measurements, a definitive decision can be made on the diamond's origin. The DiamondPLus performs best on high colour type-II diamonds and the referral rate may increase as the strength of the brown colour increases.

DiamondSure | Model# .

This compact screening device will determine natural diamonds from synthetics and simulants. Both loose and mounted polished goods in the 0.10 – 10cts size range can be tested. The instrument is intended for colourless or near-colourless goods, although it will distinguish yellow synthetics from natural cape yellow diamonds. Other fancy colours will give a high referral rate and are not recommended. Loose diamonds should be placed table down on the fibre optic probe and the test button pressed. Around 98% of colourless and near-colourless diamonds will ‘PASS’ and require no further examination. All synthetics, simulants and around 2% of natural diamonds (type II and IaB) will register as ‘REFER FOR FURTHER TESTS’. Further tests can be completed using our DiamondView. For mounted goods the sample dish can be removed to release the fibre optic probe. This can then be used in combination with the ‘auto-detect’ function to test individual diamonds within a jewellery setting.
