Drop the loose diamond into the glass of water with care. If the stone dips, you know it's a genuine diamond. It's a false diamond if it floats beneath or on the surface of the water. The reason for this is that genuine diamonds have a high density, but imitation diamonds do not. Thus they tend to sink.
Genuine diamonds are also colorless or slightly colored (usually white or brown). Imitation diamonds can be colorless or have any hue from yellow to red. They may also be treated or natural pearls with an aspect similar to treated diamonds. However, there are other factors such as price that will influence what type of jeweler will want to sell you a diamond.
Diamonds are the hardest substance in the world. This fact was used by scientists to create tools out of diamond that humans could not previously create. Diamonds are formed inside stars when carbon atoms combine together with other elements such as oxygen or nitrogen. These elements are extracted by miners who search through soil contaminated with rock dust created during geological changes many years ago.
Due to their rarity and expense, most people only see diamonds in movies or magazines. But they are found in nature everywhere from South Africa to India to China. There are several ways to identify a diamond including its shape, weight, and color. A diamond may have other gems set in it such as emeralds, rubies, or sapphires.
To see whether your diamond is genuine, hold it up to your lips and, like a mirror, fog it up with your breath. If the stone remains fogged for a few seconds, it is most likely a forgery. Because condensation does not adhere to the surface of a genuine diamond, it does not fog up quickly.
Simply immerse the loose stone in water. Because loose diamonds are so thick, they should sink to the bottom of a glass of water if dropped in. Because they are less thick, many diamond imitations, including glass and quartz, may float or sink more slowly. Always check with a gemologist before you buy a diamond.
However, if you wear your diamond ring all the time, it can be worn down by constant movement and use. This will cause the diamond to need cleaning or polishing. If you don't clean it regularly, the dirt will scratch the surface of the stone preventing it from reflecting light as well as it could. Also, some chemicals used during cleaning processes might remove the superficial coating of metal that protects the diamond's surface. In this case, the diamond would need to be re-coated. The re-coating process involves covering the diamond with layers of other metals or compounds. These can include gold, silver, platinum, or carbon. The goal is to produce a smooth finish that doesn't show the original texture of the diamond itself.
Real diamond jewelry tends to be more expensive than its imitation counterparts because they are made up of multiple gems set into one piece. Imitations often use cubic zirconia or glass for their stones. While these materials can look like diamonds on the outside, they aren't actually diamond inside. Only real diamonds can truly reflect light and create sparkle.
