Answer: Yes. It is quite difficult to tell the two apart especially when both have very similar properties. Even many professional jewelers find it hard to distinguish the two. Answer: Yes, most definitely. As seen on 20/20, Moissanite is the only other jewel that will test “positive” as a diamond when tested using a standard diamond tester. See similar questions...

Wow! Am I ever asked this question a lot. Not a day goes by that someone doesn’t ask me if they got the real thing. This question has been so popular I’ve devoted a whole article to all the tests and tricks you can perform on your stone to know if you got the “Real McCoy.” to be magically transported to the article. Hands down cubic zirconia (c.z.)is the most popular simulant on the market. There are two types: machine-manufactured and hand-cut. See similar questions...

Answer: Moissanite has very close characteristics to diamond. The refractive index or brilliance of Moissanite is 2.65 as compared to 2.42 for diamond. The dispersion or fire of Moissanite is 0.104 as compared to 0.044 for diamond. Moissanite is the second hardest jewel after diamond with a hardness rating of 9.25 as compared to 10 for diamond.

Answer: Moissanite jewels are lab created Silicon Carbide material and has very close physical properties to diamond. See similar questions...

NO! - Though Moissanite looks like a fine diamond, it is not a diamond simulant or diamond substitute. Moissanite is a jewel in its own right with its own unique properties. See similar questions...

Moissanite is a different jewel than diamond. While it might initially look like diamond, Moissanite has a different chemical composition and its visual properties of fire and brilliance are different than diamond. As such, Moissanite is not graded using the diamond grading system. All Moissanite is near-colourless and it is a beautifully brilliant, highly dispersive jewel that is eye-clean and stand on its own. See similar questions...

Bloom refers to the slow rising of "essential oils" to the surface of a cigar. It first shows up as tiny (almost microscopic) crystals on the surface, and can eventually make a cigar look slightly "dusty" with a whitish finish on the surface. Not only is it harmless, some prefer to see a little bloom, as an indication of strong taste. Mold OTOH, is (ick!) a fungus, growing on overly humidified stogies. See similar questions...

The answer is a resounding NO – Moissanite is not a substitute for diamond scientifically or emotionally. Charles & Colvard created Moissanite is a unique near-colorless jewel (SiC) that stands on its own when it comes to superb fire and brilliance. From a scientific standpoint, the Moissanite used in jewelry today is a created jewel that was originally discovered in its natural state in the Canyon Diablo meteor crater located in Arizona.

Answer: Moissanite will require only simple care just like any other jewels. You would care for Moissanite just the way you would care for diamond. See similar questions...

Answer: Moissanite is sold by stone millimeters (mm) and/or diamond equivalent weight and not by its weight. The same size of Moissanite stones as compared to diamond by weight, weighs approximately 13% less than diamond. See similar questions...

Answer: Under extreme temperature, Moissanite has more heat resistance than diamond. Just like diamond jewellery, Moissanite jewellery can be cast in place and will not be prone to any heat damage when the jewellery is being repaired or re-sized. See similar questions...

Answer: Particles of the material were originally discovered by Dr. Henri Moissan during his work at an ancient meteorite crash in the Diablo Canyon in Arizona in 1893. This meteorite crash happened approximately 50,000 thousand years ago. This amazing brilliant and diamond-like material discovered by Dr. Moissan was from the fragments of the meteorite. It was named “Moissanite” in honour of Dr. Moissan in 1905. See similar questions...

Answer: Moissanites are “H to J” in colour which is similar to many diamonds which also fall into this range of colour. It is still considered as a white colour, however not as white-white like other synthetic diamond such as Cubic Zirconia which is less believable since white-white colour diamonds are extremely rare.

Answer: Moissanites are typically VS1 in clarity when using the diamond grading system as a benchmark. See similar questions...

Not without testing the gem to see what the heat conductivity is (a diamond can conduct more heat,) or they must remove the gem from the mounting and weigh it (a cubic zirconia weighs about 1.8 times heavier than a diamond.) These are the traditional tests that must be conducted to tell the difference. There have been many instances to see if jewelers can tell the difference just by examining the gems with the naked eye. Over and over again, it was inconclusive. See similar questions...

The truth is you can't. Only an expert with special equipment can verify that a diamond is real. If the diamond is loose, try to place it table down on a blue ink line drawn on a clean white piece of paper. If you can see the line through the stone than it's a fake. But once again the sure way to tell is by using an expert with his special equipment. See similar questions...

Yes. Near-colorless created Moissanite has many similar physical properties to those of diamond. Consequently, prior to Moissanite's initial release in the market, Charles & Colvard developed handheld testing equipment (Tester Model 590) specifically designed to easily distinguish Moissanite from diamond. Because of its rarity, unmatched beauty, and patent protection, Charles & Colvard created Moissanite is expected to retain or increase its value over time. See similar questions...

No. The standard GIA diamond color grading scale is not designed to rate Moissanite. Unlike diamonds, which range from colorless to brownish to fancy yellow, Charles & Colvard created Moissanite can have slight undertones from green to yellow to gray. It is a beautifully brilliant, highly dispersive jewel that stands on its own, creating a unique jewelry category. See similar questions...

Since moissanite is slightly less dense than diamonds, it is better to refer to moissanite stones in terms of size. However, we understand that most people understand gemstones by carat rather than mm. Here is a chart: Note: For the list of corresponding carat weights to mm sizes for other moissanite stone shapes, please visit our loose moissanite stones page. See similar questions...

A diamond is made entirely of carbon (just like the graphite in a pencil). But, while graphite is very soft, the carbon atoms in diamond form in such a way as to create the hardest known substance. This special structure allows diamonds to take a superior polish and project more brilliance than any other natural colorless gemstone. See similar questions...
