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.

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.

Yes! Glass is only about a 6.5 on the Mohs hardness scale. Ziamond's Russian Cubic Zirconia is much harder, therefore it can easily scratch glass.

There is no comparison; Moissanite is a premium Luxury product with incredible Luster and heavenly beauty that is a permanent feature, irrespective of the wear and tear. Unlike CZ, which is a very heavy, has poor luster, According to the trade it is an extremely poor imitation of diamond and has a fake appearance to it.

A cubic zirconia is a man-made gemstone, which has the appearance of a diamond. They can be coloured/ dyed to resemble other gemstones. Cubic zirconias are durable but they do not have the life expectancy of a diamond.

Our cubic zirconia is considered top grade diamond simulant. We also have a lifetime guarantee against dulling.

Definitely! The many different grades are based on the purity of ingredients, the proportions of the formula, and the temperature and pressure at which the elements are combined. Each stage is critical in the production to ensure the best outcome. Ziamond utilizes only the finest grade cubic zirconia, the original Russian formula. Nothing! The only difference is that one is created in a laboratory and the other is created by nature.

Since cubic zirconia is slightly less dense than diamonds, it is better to refer to cubic zirconia stones in terms of size. However, we understand that most people understand gemstones by carat rather than mm. Here is a chart:

Answer: Unlike Cubic Zirconia, Moissanite will not fracture, crack or discolour when exposed to extreme heat. Also, it will not fade and cloud and will last forever.

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.

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.

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.

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.

Almost. We pride ourselves on the ability to be able to design any piece of jewelry. However, there are occasions where legal issues (i.e.: patents, trademarks and copyrights) will prevent us from matching an item to exact detail. Ziamond will always offer our customers many different options that they may consider.

Because colds and flu share many symptoms, it can be difficult (or even impossible) to tell the difference between them based on symptoms alone. Special tests that usually must be done within the first few days of illness can be carried out, when needed to tell if a person has the flu.

Although there are slight differences in body conformity, finclips are used to positively identify the strains of steelhead. This is why all steelhead stocked into Root and Kewaunee Rivers (brood streams) are finclipped. Knowing the strain of the fish prevents breeding of one strain with another.

This water meter measures household water usage in cubic meters, with three decimal places plus a dial showing a fourth. There are 1000 liters in a cubic meter, so the seven-digit number is in liters. The liter was originally defined in 1795 as a volume equal to a cubic decimeter, just as it is now. But in 1901, the liter was redefined to be the volume occupied by a mass of 1 kilogram of pure water, at its maximum density and at standard atmospheric pressure.

It varies on wind speed but is equal or greater than the required exhaust vents on the market when used at the soffits. CFM is very hard to compare apples to apples because of all the different variables. Everything would need to be exactly the same for the tests: Outside and Inside Temp., Pressure, wind, same ridge vent, same shingles, same inside living space conditions, same sun rays, etc. etc. etc……..That is why we feel that the industry has chosen NFA to compare products.

We don't reccommend NN resampling unless you need precise values for pixel radiometry. NN resampling leaves pixel values unchanged, but produces blocky, imprecise geometry.

A trained jeweler can tell if a diamond has been clarity enhanced by studying the diamond under magnification. It is hard to detect the enhancement without 10X magnification.
