How To Know You Are Buying A High Quality Cubic Zirconia Ring

By Jerri Perry


Many people admire the dazzling beauty of cubic zirconia jewellery and also appreciate its affordable prices. Much like buying real gemstones, man-made CZ's can also differ in quality, which means that it's useful to know how to identify the positive attributes of a piece worth purchasing. Some look so much like a real diamond that it's hard to tell them apart. These guidelines will make choosing a high quality cubic zirconia ring an easier task.

If one is searching for a CZ that is a dead ringer for a diamond, it's best to select one that does not give off excessive color flashes in rainbow hues, as these stones tend to do. The top quality pieces will instead emanate white or blue light alone, which is most similar to a actual diamond.

Grades of quality apply to CZ's as they do with diamonds. The finest specimens are known as "AAAAA", and resemble diamonds the most with regards to hardness and how much white light they reflect. Most costume jewellery is set with lower grade stones such as "A" or "AA", but there are some pieces which are typically more expensive and have higher grade CZ's.

Clarity is another factor to keep in mind, also the same as when one is purchasing authentic diamonds. This refers to how transparent the stone looks to the eye. The best specimens will allow one to see right into their centers, while those which are lower clarity have a more opaque appearance, which is usually the result of an imperfect manufacturing process. Clear stones are nicer looking and also last longer.

If cubic zirconias are ever described as "synthetic diamonds" by a seller, this is not to be taken as truth. Although both CZ's and synthetic gemstones are man-made, they are not equivalent to each other. A true synthetic gemstone needs to have all the same gemological and physical traits as a diamond, and a CZ has its own traits, so it cannot be accurately referred to as synthetic diamond.

The hardness of the stone matters as well. Gemstone hardness is measured using the Mohs scale, with a diamond exhibiting maximum hardness with a score of 10. AAAA and AAAAA CZ's generally have a rating of about 8.5 which is also quite good, but those poorer grade ones with a rating of 6 are much more likely to get scratched, especially when worn on the hands.

Besides clear stones, CZ's also come in an array of colors resembling those of precious and semi-precious stones like emeralds, rubies, sapphires, and amethysts. However, they are not intended to be worn as an imitation version of these stones, but rather for their own unique style. Although they may look as though they are copies of gemstones, they have a lot more sparkle that real and even synthetic gems do not.

Choosing a high quality cubic zirconia ring can be done more successfully when one keeps these basic points in mind, however it is also a fairly subjective issue, since personal taste has much to do with it. A ring need not look exactly like a diamond to appeal to someone's eye, the most important thing is to always buy pieces one will continue to wear happily for many years.
