    2. Performing a test with your Synthetic Diamond Screener II The Synthetic Diamond Screener II works accurately with known colorless diamonds of color D to J. You should ascertain if your stone is a diamond first, before using this device.

  • Page 17: Screener

    Testing is performed under the lid of the Synthetic Diamond Screener II where a testing area is marked by a hole in the center and a protruding overhead UV light source (Fig 2.2). The stone is placed covering this hole and testing begins when the lid is closed and the “Start Test”...
  • Page 18 2.1 For testing on loose diamond Ensure your loose diamond stone is wide enough to cover the testing area. It should be approximately 1.5 mm in width. Your diamond should also not exceed 5 mm in height to ensure that the UV wavelength transmitted by the UV light source can be accurately measured.
  • Page 19 Release the lever to lower the UV light source and secure the diamond in place for testing. (Fig 2.4) Fig.2.4 Adjust the UV light source with lever to secure the diamond in place If you are testing multiple loose stones, use the metal bar provided to hold the light source in place so that you do not need to keep adjusting the lever in order to position the loose stones (Fig 2.5).
  • Page 20 2.2 For mounted diamonds Ensure that the stone is set with an open-back setting, meaning you can still see a clear view and colour of the stone when you view the back of it and it is not obscured by the jewelry metal or other stones. (Fig 2.7).
  • Page 21 If your mounted open-back diamond is in a ring, place the ring in the centre of the cross-hair marking Ring Guide that is embossed on the UV light source. The table of the mounted diamond should be directly facing down on the testing area. With the ring hung within the Ring Guide area, use the lever to lower the UV light source to secure the stone over the testing area (Fig 2.8) Fig.2.8 Using the Ring Guide on the UV light source...
  • Page 22 2.3 Start Test The “Start Test” button located at the top right corner of the device serves as an indication when the device is ready for testing and the interior UV light source is activated to begin the identification procedure. You should only begin to use the device for testing when the “Start Test”...
  • Page 23 2.4 Important Notes about Performing a test • Ensure your tested gemstone does not exceed 5 mm in height and its width covers the Photo-detector completely. The carat equivalent of this is approximately 0.02 to 10 carats. • Conduct prior supporting tests to ascertain the stone for testing is a diamond.

  • Page 24: Reading Test Results On Your Synthetic Diamond

    3. Reading Test Results with your Synthetic Diamond Screener II The SDS measures the UV absorption ability of the diamond and this measurement is communicated as ‘Natural’ or ‘Type IIa Diamond’. After the “Start Test” button is pressed, the button will start to blink in blue as testing is underway.
  • Page 25 Blue Bar of light/Natural The first bar on the left will indicate the ‘Natural’ reading and will be lit in blue (Fig 3.2). Fig.3.2 ‘Natural’ Reading The blue light labelled ‘Natural’ indicates the UV light absorption ability of the tested diamond stone is high as there are trace elements within the stone that has absorbed the UV light, thus allowing very little UV light through to the photo-detector.
  • Page 26 Red Bar of light/Type IIa Diamond The first light bar on the right will indicate ‘Type IIa Diamond’ and will be lit in red (Fig 3.3). Fig.3.3 ‘Type IIa’ Reading A ‘Type IIa Diamond’ reading means the UV light absorption ability of the tested diamond stone is low and this is due to the lack of trace elements such as nitrogen within the colorless diamond, allowing the light to pass through the diamond with little obstruction.
