GEMTEK Diamond Detector - Desk Model;


It has an ON/OFF switch & light, a ready/test light and a test point for the probe.


Some detectors have a flimsy wire probe tip that break easily and require a costly replacement;

but this probe’s point is somewhat similar to a ball point pen; it will never have to be replaced.


Comes with an 18Volt, 1Amp, DC power supply; so no battery hassles and always ready to go.


It is very basic and simple to operate.  No special training is required.

Step by step instructions are displayed on the front panel.


Stones can be tested very quickly, even whilst set in jewellery and no need to clean the stone.

If the test is negative, then the stone can NOT be a Diamond.

If the test is positive, then it is likely to either be a Diamond or a Moissanite.


Thermal Conductivity, as measured in Watts/Metre/Celsius (approx); Plastic is less than 1, Glass is 1, Cubic Zirconia is 10, Sapphire is 40 and Diamond 1000 to 2200.

Although Sapphire has the highest thermal conductivity of any gemstone after Diamond, the difference is quite huge.  That is why a thermal conductivity test is so reliable, and convenient!!)

 

The Diamond Detector may also be helpful in separating metals that have a high heat conductivity, like silver and copper, from low heat conductivity metals, like gold.

It’s especially useful for quickly identifying gold plated Silver  items.

(Metals thermal conductivity: alloyed Titanium 5, pure Titanium 15, Stainless Steel 15, Bronze 25-50, cast Iron 30-35, pure Lead 30-35, Nickel 90, Brass 110-125, pure Gold 315, Copper 350-385, pure Silver 410-430.  Alloyed Gold can change it’s thermal conductivity quite significantly.)  

     

For 240V:  Detector A$50.00 + Power  supply A$25.00 + Postage A$15.00 + GST = A$ 99.00

For 120V: Detector US$40.00 + (Suitable adapter required) + Postage US$30.00 = US$ 70.00
