A cubic zirconia is a great way to get the sparkling look of a diamond with a noticeably smaller price tag. Crafted with zirconium oxide in cubic form, cubic zirconia jewelry, also known as CZ, is the most popular diamond alternative because of its dazzling appearance and realistic, diamond-like shine.
Like in diamonds, cut, quality, and color affect the grade of cubic zirconias. An AAA-rated CZ stone will surpass a lower grade piece in symmetry, luster, and shine. The AAA rating is the most popular grade for high-quality fashion jewelry.
The cubic zirconia has a hardness rating of 8.5 on the Mohs scale, meaning that this gem does not scratch easily. The AAA cubic zirconia is very easy to maintain. Learn more in our guide on caring for cubic zirconia jewelry.
