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$25.00=A$ 100.00
For 120V: Detector A$50.00+Postage A$25.00=A$ 75.00
(Suitable adapter is required for 120V)

THE PROCESSES INVOLVED IN MAKING THESE 8X6 OPAL TRIPLETS:
1. Search for, and hopefully find, Opal bearing ground in the Central Australian desert…
2. Dig up the Opal in up to 45C heat!
3. Slice the rough Opal into paper thin slices
4. Purchase optical glass tops from overseas
5. Purchase microscope glass slides to support the Opal slice
6. Purchase special glue, waterproof black ink etc…
8. Paint the glass slides black
9. Glue the Opal slices on to the glass plates
10. Glue the glass tops onto the Opal
11. Trim and shape into calibrated size…
…and all for just A$0.50 each!!!
If you can find 8x6 mm Opal Triplets,
made from NATURAL Australian Opals,
at a LOWER price than ours…
then don’t hesitate…
BUY THEM!
Whilst on the cost of things, ponder this;
Oil companies spend billions looking for oil, drilling out in the deep oceans or in deserts, in all sorts of weather, under dangerous conditions, pumps up the oil, build hundreds of miles of pipe lines, cart the crude oil away in supertankers which costs hundreds of millions, refines the crude oil into petrol in huge, complex and expensive refineries and then petrol tankers cart the petrol around the entire country to service stations so that we can conveniently get our petrol.
Meanwhile, some smart operator drives a second hand petrol tanker to a local spring, fills up the tank, drives to a shed where the water is filled into plastic bottles, then carts them to local supermarkets and shops so that we can buy a litre of water for $2.00 - $3.00, even more…
So; why are we complaining about the price of petrol at $1.60 (+-) per litre…???
And, not complaining about the price of bottled water… priced at about 1,000 times the cost of… well… WATER from the TAP?
It’s a mystery…
And this one;
The average daily cost for electricity, per day, for a single person, is $3.50.
The average daily cost for a couple is $4.20 or $2.10 each…
One coffee a day cost TWICE that much… even more!
So, considering the many ways by which we benefit, during 24 hours, from that $2.10 and the rather brief pleasure gained whilst drinking a $4.50 cup of coffee, we obviously would not be complaining about electricity prices, but rather the price of coffee…
would we not…???
And this one, as well…;
When we are heating up leftovers from yesterday’s dinner, that is re-heating the dinner.
But, when we are heating up a Sapphire or Ruby, which was created under extreme heat in the first place, we are referring to them as only being “heated”, not re-heated…
In fact, if not heated by man after being dug out of the ground, it is referred to as “unheated” which clearly is not the case when considering it’s origin…
Likewise; referring to a Sapphire or a Ruby as being “natural” to indicate it has not been heated by man, is also rather confusing as all stones made by Mother Nature are obviously naturally made and clearly “natural”.
Even after having been somewhat “modified” by man’s heat treatment, it’s creation is still nature and it remains a natural stone, as opposed to a “man made”, synthetic stone.
