Cubic zirconia (also known as CZ) is a synthetic crystalline substance used as an alternative to diamonds. The man-made material is colorless, hard, and flawless. Its popularity stems from its similarity to diamonds in brilliance and crystal clarity while still being affordable.
Cubic Zirconia that are rated AAA are usually more highly polished than A grade stones. They tend to have more luster and shine. However, they don't have the level of finishing and facets of AAAAA grade stones. ... AAA Grades are the most popular grades on the market for CZ's because of price and availability. Like diamond, we use 4C standard to choose from stones, cubic zirconia also have a range of colors in the gems market, like blue, pink, purple, champagne, green and more.
A good way to clean your cubic zirconia is to use a small soft brush and hot soapy water to remove dirt. Rinse it in warm water and pat dry with a clean cloth. This will restore the cubic zirconia stone to its natural shine and clarity.
