These are AAAAA quality Oval Cut Cubic zirconias.  Up until recently AAAAA was the highest quality, but now I sell 6A quality cz's if you are looking for higher quality.  These 5A stones are now a budget option, for excellent quality at a cheaper price than the highest quality.  Please note that the A rating is not a standard measurement of quality and 6A quality from one seller can be 3A from another seller.  I try hard for the A quality to match what is in the market.

The material Cubic zirconia matches the visual properties of a diamond more perfectly than any other simulant material, but the cut of the stone is just as important as the material.  There is no point buying a diamond simulant that is poorly cut because a diamond would never be cut that way.  Low quality cz material can fade in the sunlight because it has microscropic air bubbles, is badly cut and badly polished. It is these low quality stones that give CZ a bad reputation.
