Cubic zirconia is the best diamond imitation in the jewelry industry. It has provided the jewelry market with a wide range of high-quality and inexpensive jewelry to beautify our lives, and even some jewelry sellers have mistaken cubic zirconia for diamonds.

When it was just developed, many merchants were cheated, and the set-up was similar to the CVD diamond some years ago. Usually, two well-dressed couples came to the counter and asked to see some 1-carat loose diamonds; because of their dress and the quality of their words, the jeweler lowered his wariness to take out the diamonds, but the couple did not buy the diamonds after viewing them but promised to think about it and come back later to purchase and then left. But when the jeweler sorted out the goods on the counter, it was discovered that some were faulty. After careful inspection, some diamonds were switched, leaving cubic zirconia as a substitute.
Cubic zirconia is almost identical to the diamond in appearance, even more, intense in fire, and relatively hard at 8.5 to 9 on the Mohs scale, which gives it excellent durability and resistance to wear and tear. Today in California, the capital of artificial gemstones, cubic zirconia is produced in many colors, red, green, yellow, etc. In some daily custom jewelry, if the diamonds on the jewelry are out of your budget, cubic zirconia gives us an excellent alternative to diamonds as colored or colorless stones set in the jewelry. In the global market, most consumers favor gold jewelry, where the rocks in gold-set jewelry are primarily synthetic. The white diamond substitute is cubic zirconia, and sometimes white topaz is used instead of diamonds.
But you must be sure exactly what you are buying. For example, suppose you see a ring in a jewelry store with amethyst or sapphire embellished with diamonds. In that case, it is essential to ask the seller whether the colorless diamonds are natural or synthetic or some other alternative. If you plan to make your own jewelry set, you may want to consider using cubic zirconia and have your jeweler order it for you. Cubic zirconia can create jewelry suitable for everyday wear without fearing losing it.
[How can I tell cubic zirconia ?]
If you are familiar with the size of a diamond (Google for “diamond weight to size ratio”) or have jewelry calipers, you can use the scope to estimate the weight of the diamond. The quality of the rough stone can be measured with a jewelry scale, which most jewelry stores will have. If it is a natural diamond, you will know approximately how much it weighs based on the size; if the weight measured based on the size of the stone is much heavier than the diamond, it is doubtful that it is a diamond. Cubic zirconia is about 75% more severe than a diamond of the same size. For example, a 1-carat round diamond measuring approximately 6.5 mm would weigh approximately 1.75 carats for the same size cubic zirconia; cubic zirconia of the same size as a 25-cent diamond would weigh about 40 cents.

[Look at the waist of the jewel]
If the girdle of a white stone is roughly polished, if it is dark white or has the feel of frosted glass, it may be cubic zirconia. However, this method is difficult for laypeople, and it takes long experience in the field to distinguish cubic zirconia from diamonds by the appearance of a roughly ground girdle.
[Testing gemstones with carbide needles]
A relatively sharp carbide needle can easily leave scratches on the surface of cubic zirconia by applying force to the tip of the needle in a direction perpendicular to the faceted surface of the stone, and then scratching the surface slightly. But a diamond is very difficult to scratch on the surface, unless it is scratched with another diamond. However, it is important to consider sensibly that you are not free to scratch on an item that does not belong to you, especially if the salesperson does not explicitly claim that the item for sale is a natural diamond.
[Check loose diamonds or set diamonds with fluorescence]
Both cubic zirconia and diamonds produce fluorescence, but the color and intensity of fluorescence are different. Usually the same batch of cubic zirconia has a very uniform degree of fluorescence, while natural diamonds only have about half of the fluorescence, especially for broken diamonds on jewelry.

This pocket-sized diamond testing pen will tell you if it’s a natural diamond or not. Although most testing methods can’t tell you exactly what it’s made of, it’s enough to prove whether it’s a diamond or not.
If you still have doubts after these tests, take the stone to a jewelry appraiser with professional lab testing equipment to verify; thanks for reading; this is Eamti, your jewelry de-mining expert.
