Does moissanite pass diamond tester?


Moissanite is, without a doubt, the most desirable diamond selection available. It’s the stone closest to a diamond in terms of its appearance and other essential characteristics.

One of the questions you could ask when purchasing moissanite is, does Moissanite get through the Diamond Tester?

The answer is yes! Diamond testers need help discovering moissanite rings. Most diamond testers measure the thermal conductivity of the stone, not its electrical conductivity. That means that testers need to be in a position to differentiate between moissanite from diamonds because moissanite is also an excellent conductor of heat.

This blog will discuss the tools to discern between the two stones and provide additional information on the differences between diamonds and moissanite.

What Is A Diamond Tester?

If someone is referring to “a “diamond tester,” the majority of people refer to the portable “pen” tester that determines the gemstone’s thermal conductivity.

The principle of the “Diamond testers” operation is based upon the reality that different stones perform heat differently. The heat will pass through diamonds differently than through cubic zirconia and glass. The tester is constructed in a manner that allows it to accurately determine if the stone is a diamond or any other precious stone.

Some testers, too, use electrical conductivity to test stones. The principle is essentially the same. When the conductivity of electricity is pushed, the tester can determine the speed and amount of electricity in the rock that is being tested.

Does Moissanite Pass Diamond Tester?

Absolutely moissanite can pass diamond tester. The diamond tester is among the most popular and fundamental gemological tools used to test diamonds. A diamond tester fundamentally looks at thermal conductivity. This means it can identify moissanite and diamonds against other gems.

But, this technique is not very effective if it is used to distinguish diamond and moissanite. In contrast to fake diamonds and other gems, moissanite is also an efficient thermal conductor. So, when you use a diamond tester to determine the conductivity of thermal energy, it is sure to appear to be an actual diamond.

Despite the many known flaws, They are an effective instrument for gemologists and jewelers. To distinguish the two gems, you’ll need another type of tester.

In light of the fact, Moissanite can indeed be (very, very) electrically conductor, specific testers for moissanite were created. Moissanite testers measure electrical conductivity, so they can examine diamonds against Moissanite since diamonds aren’t electrical conductors.

If you’ve determined that you’d like to purchase diamond testers, There are a variety of things to be looking for.

First, ensure that the instrument uses electrical conductivity to distinguish that a diamond is a moissanite.

Another great feature is the metal detector that alerts you when you accidentally contact a portion of the setting made of metal in place of the stone.

Many diamond testers are multi-testers that test electrical and thermal conductivity. Multi-testers are undoubtedly much more costly, but they will be able to get precise results.

Other Options for Testing Your Moissanite

There are many effective ways to test for moissanite. A professional can quickly determine the distinction between a diamond and a moissanite by examining the stones under magnifying. Moissanite displays “double refraction,” while diamond has one Refraction.

We will not go too deeply into the research that goes into it but put when a single light beam enters the crown of refractive gems, twice as large, two rays of light will emerge.

A single refractive stone, like a diamond, would be able to see one light beam entering and then remain intact until it departs in complete harmony.

However, only experienced eyes can see it clearly under a magnifying lens 10x. When looking at the side components of the Moissanite under magnification, the culet will appear doubled or fuzzy. Diamonds don’t show this characteristic. Therefore, this is a straightforward method to assess Moissanite.

Based on only the naked eye. The best method of determining the difference is to possess an identical-sized diamond and examine them side-by-side. You’ll notice that moissanite, like diamonds, has a distinct fire.

In gemology, “fire” describes the bright flashes (or flashes) you can see as you move the ring in the lighting. Moissanite’s refractive index is significantly greater than diamond’s, which is why Moissanite is more attractive. Moissanite creates flashes of rainbow shades when you move it around. The disco sphere effect is more apparent when it is in sunlight.

As with diamonds, the bigger the moissanite, the greater the amount of color it can be seen and the simpler to tell it from diamonds. Based on the quantity of fire exhibited by the stone in question is more difficult when the stone’s size decreases.

Another low-tech way to differentiate diamonds from Moissanite is by the weight of the stone and dimension measurements. This requires the stone to unloose.

Moissanite is about 10 percent lighter than natural diamonds. If you decide to weigh and test the weight of a diamond or Moissanite, you can distinguish them.


In the end, if the test of warmth conductivity is used, it’s often challenging to distinguish moissanite from the diamond. Moissanite is a (slightly) electrical power conductor; however, this distinction is only detected using specialized equipment.
