If you've inherited or received a gift of gems or jewelry, you're probably wondering whether the stones are real diamonds, other white gems, or manufactured imitations. If the facet edges of your gem are rounded, it's certainly not a diamond. However, most imitations can have sharp facet edges. GIA uses the 4cs to determine diamond quality: color, carat weight, clarity, and cut. In addition, GIA may evaluate the diamond’s fluorescence, polish, symmetry, and proportions. 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 not familiar with these nuances and have no known diamonds to compare with test stones, this isn't the best way to spot a fake diamond.

This is to anchor the bait in amongst the turbulence of big fish feeding in shallow swims. We recommend: Cleaning a floating diamond ring is no different than cleaning any other type of ring. Use warm water, gentle soap, and a soft brush to scrub. Pay special attention to tight areas, like where the metal and stone meet in a tension setting. Then rinse and pat dry with a soft cloth.

Another method to determine if your diamond is real or fake is to use a lighter to light the stone for about 30 to 40 seconds before dropping it in cold water. If it's a fake diamond, it will shatter to pieces but a real diamond won't have a reaction to it. This is because weaker materials will not be able to handle the rate at which it expands and then contracts due to the heat of the fire. Real diamonds, however, have been formed under intense pressure and heat underground from billions of years ago. While this is a more accurate way to test a stone's authenticity, it can be dangerous to use fire, so be sure to use proper safety measures and use heat-resistant gloves when handling the diamond.
