6A Diamond Simulant Quality Cubic Zirconia for Gold Jewellery. 

Unless otherwise stated you are buying just 1 gem.
These stones are cut to the highest standard from the highest quality CZ material which makes them a lot more expensive than other CZ's. If you are looking for cheaper stones then please check my shop for 5A or 3A quality which are a lot cheaper.


6A Quality: A few years ago (2017) 5A quality was the highest cubic zirconia grade possible, these stones were cut from flawless cz material that did not fade over time, they were cut using laps that were accurate to 0.02mm by the most skilled gem cutters. 6A stones are cut with the same skilled gem cutters with improved machines, but this alone would only make them 5A, the 6A stones are cut with material that has been tweaked in various ways so that it matches a diamond even more closely.

There are 7A stones and 8A stones for sale on the internet, but these are just the 6A stones described above. There is no official standard to grade CZ stones, so sellers can just call them whatever they want, but I try to be accurate with the unofficial grading system, from the gems I sell:

AAA - Good Quality, used to be the highest available
AAAAA - Excellent quality, cut with machine assistance for accuracy, perfect CZ material
AAAAAA (6A) - Excellent quality with special CZ material
