What's Difference of Cubic Zirconia Quality Grade A-AA-AAA-AAAA-AAAAA

Cubic zirconia, the cubic crystalline form of zirconium dioxide (ZrOS), is considered to be the top grade diamond stimulant available on the market today.  Like most gemstones, it is available in several different grades.  Much like a diamond, the conditions under which a particular loose cubic zirconia stone was created will affect its quality.

In general, grades of cubic zirconia are based on the purity of their ingredients as well as the proportions of the formula used when they were synthesized, and the temperature and pressure at which the elements are combined. There are two ways to cut a loose cz stones,include Machine Cut and Hand Cut. Hand-cut cubic zirconia stone is individually cut with great precision and small sample order, Machine Cut is for mass-produced in large order and make sure delivery on time.

Cubic Zirconia comes in 5 grades beginning with A quality which is the most basic.  While AA, AAA, AAAA, and AAAAA are all represent good quality, as the A’s become progressively more abundant, even higher quality is represented.  Grades AAA through AAAAA are more likely to have more sparkle and are often guaranteed to last longer.  In addition, the higher the grade of CZ stone, the more its luster will be as well. CZ grade is dependent on the technique and the experience of the professional cutting the stone. Each our CZ stone is painstaking cut, by highly trained professionals, giving them the brilliance of fine diamonds.

Unlike most diamonds, all CZ stones are optically flawless and quite durable and resist scratching with normal wear.  They are relatively hard at about 8 on the Mohs scale, much harder than most natural gemstones according to the scale, such as ruby, emerald, peridot, citrine and sapphire. Discovered in 1976, the low cost and durability of cubic zirconia has made it a great competitor to the diamond ever since. As a matter fact, CZ is more luster, sparkle and shine than a real diamond. 

When choosing a CZ stone, jewelers and jewelry designers must not only take into account the size, shape, and cut, but should also carefully consider which grade of CZ will be best fitting for a particular piece of jewelry.
