    Presidium in collaboration with the renowned Gem and Jewelry Institute of Thailand (GIT) near the traditional source hub of rubies, the Synthetic Ruby Identifier is a breakthrough in the development of gemological instruments, as it is the world’s first and only tool, aside from expensive laboratory equipment, that identifies certain common synthetic rubies.
  • Page 4 The Synthetic Ruby Identifier features a deep-wave UV light that is activated to pass through the ruby towards the photo-detector on the base platform. Bars of coloured light on the front of the lid will provide an easy reading that indicates if the UV light transmittance ability of the tested ruby is high or low.
  • Page 5 The capabilities of the Synthetic Ruby Identifier are as follows: • Help to identify most synthetic flame fusion rubies • Tests on rubies within a range in dimension from 3 mm in width and up to 6mm in height (approx. 0.1 to 6 carat size) •...

    Synthetic Ruby Identifier 1.1 Powering up your device The Synthetic Ruby Identifier can be powered either by the use of batteries or through the USB cable connected to the Presidium Universal Power Adaptor that are both included with your product, or to an external power source.
  • Page 12 You may also connect the other end of the USB cable directly to an external power source (e.g. computer, laptop, etc). It is recommended you use only the USB cable and the Presidium Universal Power Adaptor provided with your product.
  • Page 13 1.2 Switching on your device To switch on your Synthetic Ruby Identifier, press and hold the Power button located at the front of the unit. A blue light will blink for approximately 20 seconds to allow the product to warm up. (Fig 1.3).
  • Page 14 1.3 Switching off your device and Power-Saving Auto-Off To switch off your Synthetic Ruby Identifier, press and hold the Power button for approximately 2 seconds until the light goes off. To ensure that your Synthetic Ruby Identifier conserves power, the unit will automatically switch off 10 minutes after the last activity.
  • Page 15 It is recommended that batteries should be removed when the device is expected to be stored for an extended period of time. Batteries do not have to be removed from the unit when the Presidium Power Universal Adaptor is used through the USB cable.

  • Page 16: Performing A Test With Your Synthetic Ruby Identifier

    Once you know your stone is a ruby, you can proceed to use the Synthetic Ruby Identifier to check if it is a synthetic flame fusion ruby. The “Start Test” button located at the top right corner of the device indicates when the device is ready for testing and activates the interior LED light source to begin the identifying procedure.
  • Page 17 Once the device is ready for testing, use the finger grips on the front of the lid to lift the lid and access the interior testing area. (Fig 2.2) Fig.2.2 Lift the lid of the device using the finger grips on the front...
  • Page 18 The testing is performed under the lid of the Synthetic Ruby Identifier where a testing area is marked by a concentric-circled base platform with a Photo-detector in the centre and a protruding overhead LED light source (Fig 2.3). Fig.2.3 The interior testing area inside the device The following instructions will guide you through testing loose gemstones and mounted jewelry.
  • Page 19 2.1 For testing on loose gemstones Ensure your loose gemstone is wide enough to cover the Photo- detector. It should be approximately 3mm in width. Your loose gemstone should also not exceed 6mm in height to ensure that the UV wavelength transmitted by the LED light source can be accurately measured.
  • Page 20 Always place the flattest face of the stone on the Photo-detector. To understand your test results, refer to Section 3 in this book – “Reading test results on your Synthetic Ruby Identifier”.
  • Page 21 2.2 For mounted jewelry or gemstones 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 2.6).
  • Page 22 With the ring hung within the Ring Guide area, use the lever to lower the LED light source to secure the stone over the Photo-detector (Fig 2.7).
