A fake diamond will have rainbow colors that you can see inside the diamond. “People have a misconception that diamonds sparkle like a rainbow, but they don't,” Hirsch said. “They do sparkle, but it's more of a gray color.
Most synthetic diamonds look too good to be true all due to their extreme brilliance. Does your stone look really bright with lots of rainbow reflected colors? If so, it's most likely cubic zirconia. Yes, real diamonds are brilliant, but they are much more subtle than synthetics.
A green, yellow, or gray glow usually means that the diamond is fake. If you don't see a noticeable glow or find that the color is very faint, the test is inconclusive. This is not a foolproof way to identify a fake diamond, so you should pair this test with several others for more informative results.
This means that diamond jewelry is often imitated and sold as a real diamond. If you have been sold a fake diamond it is most likely to be CZ (Cubic Zirconia), an imitation created in a lab. While some choose to knowingly buy and sell CZ gems, others attempt to exploit the industry and sell them as real diamonds.

A dirty stone doesn't sparkle because light simply can't enter the diamond and causes it to appear dull. So, if you notice your diamond jewelry getting cloudier overtime, it's likely due to a dirty surface and there's an easy fix to restore their luster.
Cubic Zirconia
They're so commonly used as a diamond look-a-like that many people will cite that all non-naturally occurring diamonds are fake diamonds are called cubic zirconias. Cubic zirconia is a lab-made synthetic substance composed of zirconium dioxide.
Moissanite looks so similar to diamonds that most people actually struggle to tell the difference between the two, even when placed side by side! The one telling difference is that moissanite will display slightly more rainbow sparkles than a diamond, as it has a higher refractive index.
Simulated diamonds are also known as diamond simulants and include things like cubic zirconia (CZ), moissanite, and YAG. They can also include some natural clear gemstones like white sapphire, white zircon or even clear quartz.
Cubic zirconia, also known as CZ, is one of the most widely used stones to imitate a real diamond. The reason for its popularity is the affordable price, which is only a fraction of what a real diamond costs.
Fake diamonds do not reflect spectral rays from the beam of the flashlight. This is because a diamond's refractive index is high; it makes the white light entering the diamond split into multiple colors before it exits on the other side of the stone.
What Is Moissanite? Moissanite is an interesting gemstone, because it is both synthetic, and a diamond simulant. It is not, however, a synthetic diamond. It is a diamond simulant because it is made to look like a diamond.
However, the diamond is less likely to shine if it doesn't have a good cut. As a result of a poor cut, the diamond will have much more of a dull appearance that can make it appear hazy, taking away from that shine that people often want when investing in diamond jewelry.
First, soak your CZ jewelry in warm water and detergent and let it sit for at least 2 minutes. Then use a soft-bristled toothbrush or a cosmetic brush to scrub the jewelry piece until an even sparkle reappears. Remember to rinse and dry the jewelry piece thoroughly to avoid leaving a cloudy residue on your jewelry.
The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of colors onto other surfaces. A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.
Fair/Poor Grade Diamond Examples
Fair and Poor cut diamonds usually have steep crowns and steep pavilion angles which gives them a really dark looking appearance. This makes them look extremely small for their carat weight. Because of their abysmal proportions, their brilliance and sparkle are horribly affected.
An ideal cut diamond shows only a few intensely bright flashes in direct sunlight. A diamond that actually looks good in sunlight splits those few flashes up into ten or twenty smaller sparkles.
The Density Test Real diamonds are incredibly dense, and often outmatch the fakes in density tests. To confirm this, fill a glass up with water and drop your diamond in. A fake diamond will most likely float on top or only sink to the middle while a real diamond will sink to the bottom thanks to its density.

Brilliance. The most obvious difference between moissanite and diamonds is their brilliance, with moissanite possessing more brilliance than a diamond. “It has more fire and brilliance than any other gemstone, meaning it has more sparkle,” reveals O'Connell.
Most brilliant diamond alternative
If you want a diamond alternative but don't want to lose out on sparkle, moissanite will be your best bet. Moissanite has a refractive index from 2.65 – 2.69, which is higher than a diamond. These stones exhibit a fiery, rainbow brilliance, making for superior sparkle.
February babies have the rarest birthstone of all. Diamond (April) is the rarest birthstone in a total of six states, while topaz (November) is the rarest birthstone in Montana, Wyoming, and Rhode Island.
Painite : Not just the rarest gemstone, but also the rarest mineral on earth, Painite holds the Guinness World Record for it. After its discovery in the year 1951, there existed only 2 specimens of Painite for the next many decades. By the year 2004, there were less than 2 dozens known gemstones.
