The best faux diamonds are moissanite, white sapphire, and cubic zirconia.

As light hits a diamond, it penetrates the diamond, bounces around and reflects within the diamond and ultimately returns light to your eye. That is the sparkle that you see. The cutting of a diamond directly impacts the amount of light performance achieved.

If you see a circular reflection inside the gemstone, the stone is fake. If you cannot see the dot or a reflection in the stone, then the diamond is real. Because a true diamond has powerful refractive qualities, light will bounce in different directions instead of a straight line.

Moissanite

Most moissanite rings do not look fake. In fact, many people can’t tell the difference between a moissanite stone and a diamond stone.

Cubic Zirconia (CZ) is an inexpensive diamond alternative with many of the same qualities as a diamond. Since cubic zirconia mimics a diamond but is not the same material, it is referred to as faux, fake, imitation, and stimulant.

Cubic zirconia is more likely to be completely colorless which is a tell-tale sign it isn’t a diamond. Another notable difference is that a diamond will have natural inclusions throughout the stone which is a sure sign it is real. These inclusions can usually only be seen under a microscope.

Lab-made diamonds typically have good clarity. Like a high-quality natural diamond, lab-made diamonds won’t get cloudy.

But, we’ve pulled together the best available testers on Amazon, so that you’re not left searching.

• DigiWeigh Diamond Testing Kit. BEST TESTING KIT.
• Presidium Portable Diamond Tester. BEST PORTABLE.
• RS Mizar Moissanite Tester. BEST FOR DETECTING FAKES.
• GemOro Diamond Tester.
• Presidium Gem Tester.

Diamond testers are one of the most accurate tools to check a diamond for authenticity. However, you should know that testers that rely on thermal conductivity can mistake a moissanite for a diamond because these two stones are very similar in the way they conduct heat.

The SSEF Diamond Tester For Blue and Potentially Blue Diamonds enables you to know if the stone is type IIb. The SSEF Blue Diamond Tester is $695. I want to. Darkfield Loupe. (Maglite not included)

ABSOLUTELY! You can have a stone that’s not a diamond beep just like a diamond. In fact, a lot of jewelry stores and customers in the last ten years have probably bought diamonds that weren’t real, and never knew it! Likewise, you can test a genuine diamond in a ring, and have it buzz like it’s not a real stone.

You will have to send your diamonds into a specialized gem lab for this test. Most jewelers and pawnshops won’t have this type of equipment but are usually more than happy to liaison the relationship between you and the lab.

Lab-created diamonds have very little to no resale value. That means if you buy a lab-created diamond, you won’t be able to reap any part of what you paid for it. For example, if you bought this 1.20ct lab-created diamond, you’d have a beautiful stone, yet no jeweler will buy it back.

Lab Grown Diamond Cost per Carat There will likely also be a difference in price between those purchased in a brick-and-mortar store versus an online shop. However, on average, the 1 carat lab created diamond price is somewhere around $800-$1,000 per carat.

There is no visual difference in Lab Created Diamonds vs Natural Diamonds. They sparkle the same, have the same types of color and clarity, and can come in the same sizes and shapes. This lack of nitrogen is one way gemologists can identify Lab Created Diamonds vs Natural Diamonds.

Not only are lab diamonds as durable as natural stones, but they’re also chemically, optically, thermally, and visually identical to earth-mined diamonds. Lab diamonds really do last forever, and there’s nothing that will dull the shine or interfere with the brilliance of synthetic diamonds.

Yes! Just like a mined diamond, laboratory grown diamonds can be insured. In fact, by choosing a lab-grown diamond, you’ll not only save money on the diamond itself, but you’ll also save money on the annual premium of the insurance policy due to the lower overall cost of the insurable piece.

IGI Grading and Prices. GIA is often held up as the gold standard of diamond grading while other labs are purported to have looser grading standards. For two diamonds of the same carat, color, and clarity grade, an IGI certified diamond is on average 12% cheaper than a GIA certified diamond.
