PRESIDIUM - Moissanite Testers Synthetic Diamond Screener II - SDS II Details:

* Enhanced with additional features, the Synthetic Diamond Screener II now tests for diamond melees as small as 0.02 carats with instantaneous results, through the measurement of UV absorption.* The Synthetic Diamond Screener II is developed by Presidium to help screen out Type IIa colorless diamond, which is likely to be synthetic and created through chemical vapor deposition (CVD) or high pressure high temperature (HPHT) syntheses, from the natural Type Ia colorless diamond.* When subjected to this deep UV irradiation, Type Ia and Type IIa diamonds each absorb different amount of UV light. Type IIa diamonds allow deeper UV light to pass through and thus its UV light absorption ability is low. This difference in the light absorption is significant enough to aid in differentiating between colorless Type Ia and Type IIa diamonds.

* Features:
1) Advanced technology that measures a diamond's UV light transmittance ability2) 2 colour coded (blue/red) indicator light bars to give a low or high reading of UV light absorption with blue light indicating Natural Diamond and red light indicating Type IIa Diamond3) Instantaneous clear results within 2 secondsBlue light to illuminate the testing pad4) A 5mm metal bar to conveniently raise the test probe for successive testing on loose stones5) Test button will blink in red to alert if the device is unable to detect any stones on the photo-detector6) Auto shutdown of interior LED light source for safe testing when lid of device is open or when Start Test button is not activated7) USB port for alternative power source and connectivity8) Exterior base foam padding to ensure non-slip sturdiness and prevent scratches to surfaces9) Low battery indicator10) Energy-saving auto power-off of device after 10 minutes without operation

* Benefits:
1) Help to screen out Type IIa diamonds likely to be synthetic diamonds2) Tests on diamonds within a range in dimension from 1.5 mm in width and up to 5 mm in height (approx. 0.02 to 10 carat size)3) Tests on polished diamonds of popular cuts such as brilliant round cut, emerald cut, baguette cut, etc4) Can be used on both loose and mounted diamonds (on jewelry with open-back setting)5) For use on colorless diamonds from D Color down to J Color

* The Presidium Gem Indicator, the only handheld tester in the industry specifically for colored gemstones, indicates up to 31 different types of colored gems based on their thermal conductivity and even features a color input function that allows users to select from a range of 12 common colors, thereby achieving more accurate results. With an easy-to-read clear digital LED screen, this smart thermal tester also comes with the Presidium patented refined changeable probe tip, which ensures minimal equipment downtime.* The Presidium Gem Indicator is an enhanced and more convenient handheld version of the revolutionary Presidium Gem Tester/Colored Stone Estimator.* The Presidium Gem Indicator probe consists of two linked thermometers; one which is heated electronically, while the other is cooled by the gemstone being tested. The difference in temperature creates an electrical output, which is then amplified and displayed on the new digital organic LED display.* It is simple to use, easy to maintain and quick in giving you intelligent results about your colored gemstones.

PRESIDIUM - Refractive Index Meter II - PRIM II - Colored Gemstone Testers Details:

* By measuring the quantity of light reflected through the stone, the Presidium Refractive Index Meter II (PRIM II) is able to separate diamonds, moissanites and other colored gemstones via the Refractive Index (R.I) of these polished gemstones.* Unlike a traditional refractometer that has a limited range of R.I measurements and thus cannot be easily used to measure R.I of certain gemstones, the PRIM II is able to measure a wider range of R.I value from 1.000 to ~3.000, therefore covering the commonly known gemstones in the market and can also measure RI of diamonds, moissanites and other diamond simulants such as high zircon, strontium titanite, etc.* In addition, a fast and clean test can be easily done with the PRIM II, without the inconvenience and messiness of R.I liquid used in the traditional refractometer.* The PRIM II also comes bundled with a CD featuring new software that provides a database of more than 50 gemstones with their various properties and possible origins, and a program that enables the user to enter known properties of the gemstone such as color, S.G. value, hardness, etc to ascertain what possible gemstone it is from the database information.
* Features:1) Pinhole-sized light reflectivity measure on wide oval platform2) Cover cup with blackout interior to ensure light reflectivity measure is accurate3) Instantly displays direct R.I reading on digital index LED display panel4) In-built Refractive Chart for referencing diamonds and simulants above R.I reading of 1.85) In-built 8-piece gemstone holder6) Pocket-sized Refractive Index Chart pull-out with R.I readings for 55 stones7) PRIM II complementary software to help users find out the possible colored gemstone using data on various gemstone properties8) Gemstone Dictionary in software with 57 gemstones' properties (R.I, Color, Hardness, S.G. Value), country of origin and related information9) USB port for alternative power source and connectivity

* Benefits:1) Estimates diamonds, moissanites and gemstones' R.I instantly, thereby allowing identification of possible stones2) Able to test wide range of R.I values from 1.000 - 3.000, more than traditional refractometer3) No need for messy R.I liquids4) Tests on transparent gemstones, with flat polished surfaces5) Continual elimination of possible gemstones via software program through input of known values such as R.I, color, hardness and S.G.6) Ideal for separation of gemstones7) Clear and visible display for ease of reading results8) No waiting time between tests9) Simple and easy to use10) Light and compact tester11) Runs on batteries or with recommended Presidium AC adaptor

* Power & Battery:1 x 9V alkaline battery (approximately 3 hours of continuous use)USB port to be used with appropriate Presidium Power Adaptor (not included)
* Recommended Operating Conditions:Optimal Operating Temperature: 18 DegreeC - 27 DegreeC (65 DegreeF - 80 DegreeF)Storage Temperature: 10 DegreeC - 51 DegreeC (50 DegreeF - 124 DegreeF)
* Dimensions & Weight:Length: 140mm (5.50 inches)Width: 80mm (3.15 inches)Height:33mm (1.30 inches)
