Take a careful look at a diamond before purchasing to ensure it is real. Unscrupulous jewelry dealers might attempt to pass off a synthetic diamond as a natural diamond. Labs can produce synthetic diamonds that are identical in chemical composition to real diamonds. Synthetic diamond differs from cubic zirconium, which is a type of gemstone that resembles a diamond. Check the physical characteristics of a diamond to help determine whether it is real or synthetic.
Things You'll Need
Weigh the diamond on a sensitive gem scale. Compare its weight with a natural diamond of a similar size. If the diamond weighs considerably more than a natural diamond, it may be synthetic.
Examine the diamond under a magnifying glass in bright light. Look for inclusions, which are small foreign bodies stuck in the diamond that look like tiny grains. Synthetic diamonds are artificially created and contain no inclusion bodies. Even a high-quality natural diamond will have one or more inclusions.
Look at the color of the diamond. Note whether color variations appear as curving bands or concentric hexagons. Curved bands of color variation occur in synthetic diamonds, while natural diamonds will show hexagon-shaped variations in color.
Assess the sparkle of your diamond. Compare your diamond to a natural diamond and determine which looks more sparkly. Synthetic diamonds often sparkle more than their natural alternatives, making this an effective way to distinguish real diamonds from fake ones.
Synthetic diamonds contain fewer flaws and sparkle more than natural diamonds. Although synthetic diamonds are worth less, they still make attractive pieces of jewelry.
