INNOVATION

SYNTHdetect

SYNTHdetect is the latest addition to our range of IIDGR screening and detection instruments.  It is specially designed for testing stones in mounted jewellery but can also be used to test loose stones.
It is suitable for testing colourless to near-colourless stones with no lower size limit.  The various jewellery attachments allow rings, bangles, brooches and necklaces to be tested.  Larger jewellery pieces, along with loose stones can be viewed in the sampling tray.
Using the principle of time-resolved photoluminescence, an image is viewed on a high-resolution touch screen and a decision can be made whether the stone is natural or synthetic.
