The International Institute of Diamond Grading & Research (IIDGR), part of the De Beers Group, will showcase what it has called its “much sought-after” PhosView screening instrument for the first time, at the UK Jewellery Conference next week.
The UK demonstration of PhosView follows the launch of the instrument at the Hong Kong Gem & Jewellery Fair earlier this month.
According to the institute, the new instrument is a compact, self-contained screening device designed to allow parcels of polished stones to be quickly and accurately analysed to determine if they contain potential High Pressure High Temperature (HPHT) synthetics.
During analysis, colourless and near-colourless stones in the 0.003 carat (one third of a point, or 0.9mm) to one carat size range are viewed on a screen while being subjected to UV light. Any phosphorescing stones are revealed and may be manually separated out for further analysis using built-in manipulator arms. The machine is designed to screen loose diamonds as well some jewellery pieces.
Jonathan Kendall, president of IIDGR, said: “Since we launched PhosView two weeks ago, we have seen a very positive response from the trade. Confidence is of paramount importance in the jewellery sector, and the efficient, reliable and cost-effective solution that PhosView provides for HPHT synthetic screening has proved to be very popular.
“We look forward to demonstrating the instrument to the UK trade for the first time at the UK Jewellery Conference, where attendees will also be able to learn about our rapidly growing polished diamond grading services first-hand.”
