Frequently Asked Questions

Does a diamond tester work on gemstones?

A diamond tester is a specific tool used to test the authenticity of a diamond. The tool works by measuring the thermal conductivity of a stone to determine if it is a diamond or a fake. Thermal conductivity tests rely on the fact that diamonds are excellent conductors of heat and therefore heat up much faster than other gemstones.

When using a diamond tester, one should be aware that some gemstones can be mistaken for diamonds. For example, cubic zirconia, moissanite and white sapphire are all gemstones with similar characteristics to diamonds. In order to be sure that a stone is a real diamond, a more comprehensive testing should be done, such as a refractometer, carat weight, or optical testing.

In conclusion, a diamond tester can be used to test the authenticity of a diamond, however it may not be reliable for other gemstones. To confirm the authenticity of a gemstone, it is best to consult a professional gemologist.

What stones will pass a diamond tester?

A diamond tester is an instrument used to determine whether a stone is a diamond or a simulant. It works by measuring the electrical resistance of the stone, as diamonds are excellent electrical insulators while simulants have lower electrical resistance. The only stones that will pass a diamond tester are real diamonds and other diamond simulants, such as moissanite and cubic zirconia.

Real diamonds are composed of pure carbon, and they have a unique crystalline structure that gives them their hardness and sparkle. Diamond simulants, on the other hand, are synthetic materials that are designed to mimic the look, feel, and characteristics of real diamonds. Moissanite is a type of diamond simulant made from silicon carbide, and it is nearly as hard as real diamond. Cubic zirconia is another type of diamond simulant, and it is made from zirconium dioxide.

In order to pass a diamond tester, the stone must be a real diamond or a diamond simulant. Natural stones such as quartz, opal, turquoise, and other gemstones will not pass a diamond tester, as they have different compositions and electrical properties than diamonds and their simulants.

What is the best gemstone tester?

The most important aspect of a gemstone tester is its accuracy. A high-quality gemstone tester should provide precise readings, so you can make sure that the gemstone is genuine and has the desired characteristics. Furthermore, the tester should be easy to use and provide quick results.

How do you use diamond tester on gemstones?

  1. Start by taking a look at the gemstone you wish to test. Make sure the gemstone is clean and free of any dirt or debris.
  2. In order to use a diamond tester, you’ll need to access the gemstone’s surface. If the gemstone is set in a piece of jewelry, you’ll need to use a pair of tweezers to hold the gemstone while you test it.
  3. Place the tip of the diamond tester onto the surface of the gemstone. Make sure that the tip of the tester is making direct contact with the gemstone.
  4. Turn on the diamond tester. Most diamond testers will have a button or switch that you can press to turn it on.
  5. Wait for the tester to finish its analysis. Depending on the type of tester you’re using, this may take a few seconds or even a few minutes.
  6. Read the results of the analysis. Most diamond testers will give you a result such as “diamond”, “moissanite”, or “not a diamond”.
  7. Once you’ve read the results, turn off the diamond tester and remove it from the gemstone.
  8. Clean the gemstone and return it to its original setting (if applicable).
