Cubic Zirconia Stone vs Diamond test

Cubic zirconia is a synthetic gemstone, produced in a lab, which mimics the color, clarity, and weight of diamonds. Cubic zirconia, also called CZ, is the most popular diamond substitute, and because it is artificially manufactured and is far less rare than diamonds, it is a feasible alternative for those who cannot afford a diamond but still want the appearance of a diamond.

Cubic zirconia is an excellent substitute for engagement rings, necklaces, and bracelets, especially if the wearer is active, prone to losing jewelry, or cannot afford a diamond. These low-cost alternatives allow people on a budget to get the diamond look, without having to pay the diamond price.

What are the similarities and differences between cubic zirconia and a diamond?

• CZ weighs more than a diamond, but the difference will be imperceptible when the stone is used in jewelry. The weight is used to, however, by jewelers and appraisers to identify the difference between CZ and a diamond.
• Cubic zirconia is found in all of the same shapes and cuts as diamonds but will create more fire (color flashes), than diamonds in those same cuts.
• Clear, colorless cubic zirconia will have no imperfections, and in some ways, cubic zirconia is identified as being “too perfect,” when compared to diamonds of the same shape, color, and cut.
• CZ can come in many different colors, just like diamonds.
• Diamonds are much harder and more durable than cubic zirconia, but some CZ is produced with a special coating that makes it harder and resemble diamonds more closely.

Does cubic zirconia come in different grades?

Though it is considered a “diamond equivalent,” and is often looked down on by those who prefer “real” gemstones, cubic zirconia has the same qualities of other stones, and can be rated in the same way, by color, clarity, cut, and carat. When it comes to rating cubic zirconia, it is important to keep in mind that these stones are formulated in a lab, and are designed to look perfect, whereas gems that come from mining operations are bound to have imperfections, and it is often those imperfections that make the stone unique and desirable.

The quality of cubic zirconia will vary based on the manufacturer and the manufacturing process. Clarity is usually the aspect of the stone that suffers when the stone has a low quality, but in some cases, that may be preferred, so that the stone does not look “too perfect” and therefore fake. In some cases, you may see CZ graded from A (low end) to AAAAA (high end), which can help you find a quality stone. Like with most jewelry, however, the best way to find a suitable stone is to hold it in your hand and look at the four C’s yourself.
