Using a loupe or magnifying glass, look at the edges of the gem where the facets meet. Are they rounded, chipped, or abraded? What do the Results Mean? A newspaper or a piece of paper with a small dot drawn on it. This test is only appropriate for loose gems, not set ones. How to Perform the Test

A temperature test can determine whether your stone is real or fake.You will need a lighter, a glass of cold water, tweezers, and the diamond you’re evaluating. Unless your stone is cut unusually shallow or deep, the weight and size should match up with the chart. If you used a ruler, keep in mind that there's some uncertainty in your measurement. And while inclusions are natural, they impede the way light passes through a diamond. The result is less sparkle, fire, and scintillation. The Gemological Institute of America (GIA) is a nonprofit organization. It is an educational institution that provides non-biased diamond and gemstone evaluations. The organization does not sell, buy, or represent diamond retailers. If you’re still unsure about whether floating diamond rings are for you, here are some pros to consider: The Center Diamond Will Look Larger

If you're in possession of a diamond ring and are questioning its authenticity, then it's recommended that you seek out advice from a reputable jeweler. But if you're in a hurry, here are simple tests that you can use at home to tell if your stone is the real thing or a fake. How to know if your diamond is real with home testing methods If the facet edges of your gem are rounded, it's certainly not a diamond. However, most imitations can have sharp facet edges. Any diamond shape you like can be used in a floating diamond engagement ring. Round diamonds are popular because they give off the most brilliance and sparkle. However, a fancy shape gemstone like an emerald or marquise would be just as lovely. On a calm stillwater you’ll generally want 0.1g in float size for every 1.5ft of water. So for example a 0.2g float is ideal for 3ft of water and a 0.4g-0.6g for 6ft of water. If its windy however, you will probably need to use a heavier float than this guide because of the increased tow. Three-digit numbers also indicate purity. Gold may be marked with "585" or "750" while "900" or "950" designates platinum. "925" means sterling silver.

The Diamond features a long, stable fiberglass stem, suitable in all conditions, that is super durable. This runs right up through the high-grade foam float body and into the bristle, making the float virtually indestructible. The body shape is where the name comes from, a diamond. This offers a balance of stability, sensitivity and low resistance. The bristle is hollow plastic, and highly visible, cut and painted in house from scratch. Perfect for supporting large baits. According to a new study, diamonds can be carried up through the lithosphere—the crust and uppermost layer of the mantle—by dense magmas rich in carbonate. If the gem shatters, it's certainly not a diamond. (It was probably cubic zirconia or glass). However, the test doesn't prove that a surviving gem is a diamond. Moissanite, white sapphire, white topaz, white spinel, YAG, and GGG all have low or no heat sensitivity and may survive this test. Previous models had suggested that gases in the magma would increase its buoyancy, helping to push the diamond-laden melt closer to the surface without destroying the precious gems. A piece of low-grade corundum (sapphire) would tell you more. If the gem scratches corundum, it's diamond, moissanite, or white sapphire.

These people are pretty smart," he said of diamond miners, noting that years of experience have taught them many rules of thumb regarding the most likely places to look. These melts are really quite special, because they can hold a huge amount of dissolved carbon dioxide, up to 40 to 45 percent by weight," said study leader James "Kelly" Russell, a petrologist from the University of British Columbia in Vancouver.

To get the most sparkle out of your center stone, we recommend you choose one with a clarity grade of at least SI1 or SI2. These diamonds will have inclusions that are visible under 10x magnification, but not necessarily to the naked eye. Diamond Color There are a few different methods to distinguishing a real stone from a fake one. The most reliable approach is obtaining a GIA report. However, there are a few simple at-home methods you can also try.

In spite of their fame as the hardest material on earth, diamonds aren't indestructible. They can chip, and diamond can still scratch diamond. So, if you've found a chip on the gem, it could still be a diamond. Nevertheless, a highly abraded surface indicates a softer material.

What You'll Need Before performing this test, make sure that your diamond is clean. To test the diamond's refractivity, place the stone on its flat side onto a piece of newspaper with lots of lettering. Make sure to use bright lighting and that no objects are casting a shadow on your diamond. If you can read the letters from the newspaper — whether they appear blurry or not — then the diamond is fake. But if the diamond is real, its facets will refract light in multiple directions instead of a straight line. Because of this, you won't be able to see through the diamond to make out the letters on the paper. Using fire to test your diamond
