1) Water Test
Here’s a straightforward method you can use at home to test a diamond. First, using a standard drinking glass fill it to about three-quarters full with water. Next, gently place the loose diamond into the glass of water. Watch closely: a genuine diamond, due to its high density, will sink to the bottom, a fake stone will float underneath the surface or at the very top.
2) Fog Test
For the fog test, hold the diamond or ring between two fingers and breath on it with a puff of air. A light fog will form on the diamond because of the moisture and heat in your breath. If the fog dissipates right away, the diamond is real. If it takes several seconds for the fog to disperse, it is likely a fake diamond. Diamonds effectively conduct heat and therefore disperse heat quickly.
3) Check Setting & Mount
If a diamond is already placed in a ring, look at the type of settingand mount that’s used. Because of a diamond’s large price tag, a real one will only be set in high-quality jewelry. For example, a real diamond will be set in materials such as white gold, platinum, yellow gold, pave or side-stone setting and halo setting rings. To see if the setting is truly as described, look inside the ring’s center for markings. As an example, the notes 10K, 14K, and 18K indicate the type of gold used. T...
When you see a diamond sparkle, you’re experiencing its ability to bend and refract light. When light strikes the pavilions (the angled surfaces on the lower half of the diamond), it is bounced and refracted up through the diamond’s table (the top, flat surface) to the naked eye. When a diamond does this well and sparkles radiantly, it is called br...
In addition to refractivity, you can test a stone based on its reflectivity. While refractivity pertains to the directions the light bounces, reflectivity refers to the amount and quality of the light that is reflected off of the stone. Reflectivity encompasses both the brilliance (white light sparkle) and fire (colored light) that shines off of a ...
While various tests can be used to tell if a diamond is real, it’s advised to have a professional diamond expert assist you in determining if a diamond is genuine. A professional gemologist who has a Graduate Gemologist (GG) degree will be able to tell you definitively if a diamond is real or not. Bringing your stone to a diamond professional will ...
Because of the increasing presence of synthetic moissanite on the market, it’s important to use the tools of a jeweler to test for genuinity. These tools can determine almost immediately if a diamond is real or fake.
The scratch test was a once widely used technique that aimed to determine the hardness of a gemstone’s mineral. The test involved scraping the loose gemstone along a mirror to see if it would scratch the mirror or the stone. While a diamond is formed with very strong materials, fakes like cubic zirconia and moissanite are quite durable and scratch-...
With the rising popularity in other gemstones, here are some steps to spotting a stone that to the naked eye may appear similar to a real diamond.
Many of the tests in this guide, like the fog test and the thermal conductivity test, can help determine if a diamond is real. But due to the number and complexity of synthetic gemstone materials, we recommend consulting a diamond expert or jeweler to review the pieces you already have in your home. These experts are trained in knowing how to spot ...
This guide is for people who own jewelry pieces or collections and want to know if they are real. If you have jewelry pieces at home or from ancestors you wish to verify, this guide will provide you with at-home tests along with tests a diamond expert or jeweler can conduct with specialized equipment. The simplest and most effective way to test a s...

4 days ago · The fog test is one of the simplest ways to check if a diamond is real. Hold the stone between your fingers and breathe on it to create fog. A real diamond disperses the fog almost immediately because diamonds are excellent heat conductors. On the other hand, fake diamonds, like cubic zirconia, will hold the fog for a few seconds longer.
Diamond Detector. If your work requires you to identify small stones in settings, a diamond tester is a necessity. Small, dirty, low-quality diamonds are impossible to distinguish with the naked eye.
