White AAAAA High Quality

Cubic Zirconia AAAAA White/ Diamond Simulant/ High Quality Cubic Zirconia

High quality Diamond Simulants” and created gems for use in jewelry making, gem collections, or just for decoration. The diamond simulants are very hard or impossible to tell from real, flawless diamonds. They are even close in hardness to a real diamond and cannot be scratched, even slightly, by any normal household item. Diamond CZ, like diamonds, can scratch glass. Cubic zirconia and other lab created gemstones are increasing in popularity and many people now consider them to be just as beautiful like their natural counterparts. It’s a common misconception that all CZ Stones are the same. Just like Diamonds, there are a number of Quality Levels, and there is a range of Price Points for these beautiful look-alikes. Cubic Zirconia stones are rated from A to AAAAAA. A is the Lowest Quality, while AAAAAA is the Highest Grade available. There’s a difference in the look and the price between the Lowest and Highest Grade, and there’s a market for them all. You should understand the difference to make the proper choice when selecting a CZ stone.

Synthesis

The Soviet-perfected skull crucible is still used today, with little variation. Water-filled copper pipes provide a cup-shaped scaffold in which the zirconia feed powder is packed, the entire apparatus being wrapped with radio frequency induction coils running perpendicular to the copper pipes. A stabilizer, typically calcium oxide, is mixed with the feed powder. The addition of certain metal oxide dopants into the feed powder results in a variety of colors. For example:

Dopant Color(s)

• Cerium – Yellow, Orange, Red
• Chromium – Green
• Neodymium – Purple
• Erbium – Pink
• Titanium – Golden Brown

AAAAA CZ stones are the top of the line. They are crafted by the best stone cutters and are polished just like any top rated Diamond would be. These stones are remarkably similar in appearance to diamonds and set in the same type of mountings as their diamond counterparts, it would be difficult to tell them apart. These pieces are high quality, yet affordable, choices for a shopper looking for a stunning piece without worrying about losing the entire money their wallet has. Following are some physical and chemical properties of CZ White AAAAA:-

Loose cubic zirconia stones are harder than other gemstones, but not harder than diamonds, sapphires, rubies, or chrysoberyl. Hardness is determined by Mohs’ scale of hardness. The highest grade of cubic zirconia is AAAAA, which measures 8.5 in hardness on the Mohs’ scale. Cubic zirconia price can be seen below for loose, round gemstones.
