Diamonds look almost the same as other gemstones, such as moissanite to name one. Many vendors take advantage of the resemblance in the appearance of diamonds and those other gems. Therefore, you may not know what you are buying. While price is an indicator of quality, lab grown diamonds come at a fraction of the cost of natural diamonds and other jewelry elements can affect the rate. This is why you sometimes need professional assistance to determine whether your gemstone is a diamond or not.
While you can do some tests, a professional assessment of diamond rings comes with a different level of trust. Here, we will discuss how a jewelry professional tests whether a diamond is authentic.
Heat Probe Testing
A test that professionals offer for free is described with the phrase heat probe. It checks how long a diamond is capable of holding a high temperature. The crystalline structure of a diamond is among its unique features. It means that while it is possible to apply heat to a diamond, the stone can disperse it quickly. It is usually performed for a few seconds and does not have any effect on a diamond.
Moissanite Test
It is possible to do a comparison between moissanite and a diamond at a jewelry location. Moissanite is a gemstone that looks similar to a diamond, so it usually takes a trained eye to distinguish the two stones. Jewelry professionals usually possess special equipment that enables differentiating the products. The same equipment can tell whether you possess a diamond stimulant or a genuine diamond. The aforementioned method cannot tell whether a gemstone is a diamond or moissanite, so this combination test is essential.
High Sensitivity Weighing
A diamond is usually a durable stone, so it is lighter than its alternatives. For instance, it can weigh up to about 55% less than cubic zirconia. Therefore, jewelers compare a diamond and cubic zirconia with this testing method. The comparison requires a genuine diamond that has the same specifications as the other gemstone.
Microscopic Examination
As a last resort, use this form of test to confirm whether a diamond is authentic or not. Think of it as a higher variety of jewelry loupe testing. Performing it requires looking at the stone with a microscope having a 1200 magnification rate. If some amount of color becomes visible when the stone is observed under a microscope, it means that it is a fake gemstone or an artificial stone.
