Its origin is zirconium oxide. Zirconium oxide is a white crystalline powder. One use of this element is in glazes and ceramic colors. When it is melted at an extremely high heat, it creates crystals, which are then polished and known as cubic zirconia. Stabilizing agents are added to Zirconium oxide to form cubic zirconia. Like diamonds, cubic zirconia is clear and colorless, with a good degree of hardness with a Mohs score of One of the reasons these synthetic stones have become famed as substitutes for diamonds is that their shapes are similar to various diamond cuts, like oval cut or fashion cut.
The gem was originally intended—like its parent Zirconium oxide—for industrial purposes. But when folks recognized these stunning similarities to diamonds, they began producing cubic zirconia stones for use in rings and necklaces. The process for doing so was perfected in the s, and brands like Swarovski started taking advantage. By the mids, more than 50 million carats of cubic zirconia were being sold for fashion jewelry!
These will be explained in greater detail below. This is your quick way to tell which one you are working with, except for the price tag of course, wink wink. Diamonds are classified by color. The grading scale starts at D and ends at Z. The D colored diamonds are clear.
The Z colored diamonds, on the other hand, are yellow. The more lack of color, the more valuable the stone. Colorless diamonds are the most valuable stones in the world.
The reason they have functioned as affordable substitutes for diamonds is that it can look like a D-colored diamonds. While cubic zirconia can be manufactured in colors, they are more commonly colorless. The difference is in the way the two reflect light. Clarity is another characteristic that sets diamonds and cubic zirconia apart.
Because of that, they often have flaws. Of ones that are of gemstone quality, there are still many that have imperfections, which are called inclusions, meaning the diamond includes tracing of other elements, which take away the clarity. The lowest clarity grade of a diamond is Included, the highest Flawless. If you are looking for great clarity, that desire may drive you toward Zirconia.
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. While these stones may look somewhat similar, the composition is very different between them. When looking to tell the difference between diamonds and cubic zirconia, consider the hardness.
A diamond is the hardest stone known to man while a cubic zirconia has a much lower rating of hardness. Diamonds are made of carbon which lends to their brilliance and hardness. You can also test it out by checking the weight. A diamond and a cubic zirconia can be the same in actual size, but cubic zirconias are slightly denser and will weigh more.
While diamonds come in varying prices due to the size or other factors determining the quality of a jewel, they will almost always cost more than a cubic zirconia. If a piece of diamond jewelry seems too low for what you are getting, ask to see the certificates to ensure it is a real diamond and not a fake stone or synthetic being passed as the real thing. While the biggest difference between diamonds and cubic zirconia is often the price, you should use your common sense.
For example, a small diamond may cost less than a large cubic zirconia stone. To spot this difference, though, you will need to look at the stones using a loupe, preferably one that has 10x magnification. Related: Click here to browse an outstanding selection of fine jewelry.

Jewelers usually have diamond testers, which are small electronic devices that can detect diamond , and if you ask to have your stone tested, you can find out the truth immediately, for a small fee.

With CZ, there are different compositions depending on how a manufacturer wants to add to their secret recipe starter powder or additives.
For the case of diamonds, there is a small variance in the density for the same reason due to impurities like inclusions. What are cz diamonds that are found in listings on eBay? Are they diamonds or not? Is it referring to a mixture of CZ and diamond in one piece of jewelry? The term CZ diamond is very misleading and is commonly used by unethical sellers to obfuscate consumers.
These sellers are labelling cubic zirconium stones as diamonds in an attempt to market them as being the same. Bear this in mind when buying at places like eBay where jewelry quality is generally low or outright bad. Besides CZ, what are other stones that look like diamonds? Have you heard of moissanite and what do you think of it compared to cz and diamond? Can you recommend some places to buy cubic zirconia rings that look real? Most of the CZ jewelry I had encountered in departmental stores look cheaply made and unbalanced.
In terms of appearance, no other stone apart from CZ will offer a close resemblance to diamonds. Instead, moissanite appears oily and is often cut badly with poor contrast patterning. Most of these stones and jewelry are mass produced by machines in volume with little priority placed on quality. Compared to moissanite, cubic zirconia is cheap and easily replaceable if it gets damaged.
In my opinion, they are a better substitute for diamonds. Click here to cancel reply. The Argyle Pink Diamonds Tender. Diamond Prices — Are You Overpaying? White Flash.
