What does a diamond tester test?
A diamond tester is a portable device used to check the authenticity of diamonds and test material for their thermal and electrical conductivity. It can accurately indicate if the stone is a real diamond based on the gem’s physical properties.
How do you read a diamond tester?
If LED lights up to the red zone with three periodic bees, the stone being tested is a diamond. If LED lights up only to the green and/or yellow zone, then the stone is a stimulate or non-diamond. If the probe tip comes into contact with metal, the diamond tester will emit a continuous beep.
What is diamond Selector?

Can a diamond tester test crystals?
It can also be used for testing sapphire, ruby, crystal, agate and other stones.
Can fake diamonds pass diamond tester?
There are different ways to diamond test. It’s important to know which tests synthetic diamonds will pass and which they will fail. Carbon lab diamonds can pass tests in terms of their physical and chemical properties, but when these synthetics pass in front of experts, their difference are quite apparent.
Is Diamond Tester accurate?
Diamond testers are one of the most accurate tools to check a diamond for authenticity. This problem is solved by using a device that uses electrical conductivity to test stones – diamonds and moissanites conduct electricity differently. Related: Check out this selection of real diamond jewelry.
What diamonds will pass diamond tester?
A diamond tester will only test positive for diamond and moissanite. Synthetic moissanite has been used as a gemstone only since the 1990s, so if your piece is from an earlier era, it’s definitely a diamond if it passes this test!
Can I test ruby with a diamond tester?
Yes! A diamond tester will also work on ruby or and other real gemstones. Diamond testers not only work on diamonds and rubies but all other types of jewelry and stones. You can test stones like emeralds and sapphires as well to see whether they are real or fakes.
Does the diamond selector 2 work?
Do Diamond Testers Really Work and How? Portable diamond testers actually do work and have proven to be very handy if you don’t know the authenticity of a diamond. A basic diamond detector uses its heated needle tip made of metal to cause a heat transference once placed on the diamond’s surface (thermal conductivity).
Do Diamond testers work on rough diamonds?
Diamonds which have not yet been cut are referred to as ‘rough’ or ‘raw’ diamonds. To identify whether the stone you have is a diamond, you can do a quick visual evaluation to rule out other gemstones. From there, you’ll want to perform a more precise test with a piece of corundum or an electronic diamond tester.
Will a fake diamond sink in water?
Because loose diamonds are so dense, they should sink to the bottom when dropped in a glass of water. Many diamond fakes – glass and quartz included – will float or not sink as quickly because they’re less dense.
How does an electronic gem tester work?
These testers worked by detecting a distinctive characteristic of diamond — it is an extremely good conductor of heat. This property has been known for a long time and was the basis of one of the oldest tests for diamond: touch a diamond to your lip and it will feel cold.
How does a diamond tester work on a diamond?
Diamond Testers. A diamond tester works by sending heat into the stone and measuring how fast the stone conducts the heat. Each type of gemstone has its own characteristic rate for conducting heat.
What kind of test does a diamond feel like?
This property has been known for a long time and was the basis of one of the oldest tests for diamond: touch a diamond to your lip and it will feel cold. Since diamond is an exceptional thermal conductor and cubic zirconia is not, the first diamond testers used a heated probe to detect heat dissipation.
Can a Presidium tester be used to identify diamonds?
The Presidium Gem Tester provides a quick, easy, laboratory proven way to identify Diamond and separate the most popular Colored gem stones from one another. This valuable tool can eliminate human error when identifying precious gems.
