However, because it’s artificially created in a lab, cubic zirconia is inherently flawless. Diamonds, on the other hand, are very rarely (almost never) flawless.
Will a cubic zirconia cut glass?
Recognize cubic zirconia. Cubic zirconia is a synthetic stone which closely resembles a diamond. However, some high-quality cubic zirconia can also scratch glass, so this test is actually not a definitive way to determine whether a diamond is real or not.
What is the difference between a cubic zirconia and a lab grown diamond?
What is the difference between lab diamonds and cubic zirconia? Quite simply, a laboratory-grown diamond is a diamond: carbon atoms arranged in a diamond cubic crystal structure. In fact, a cubic zirconia contains zero carbon, whereas diamonds (mined and grown) are made entirely from carbon.
What are VVS CZ diamonds?
