CUBIC ZIRCONIA WHITE DIAMONDS - ZIRCONIUM MATERIALS



                Cubic zirconium (or CZ) is based on zirconium oxide (ZrO2), a mineral that is extremely rare in nature but is widely synthesized. Generally, Cubic Zirconium is the name given to the family of monocrystals, created on the base of high temperature oxides. The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors.

Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconium has been the most gemologically and economically important diamond simulation. It can be produced either transparent or opaque in nearly any color and can be faceted in many cuts. Its main competition as a synthetic gemstone is the more recently cultivated material moissanite.

Cubic zirconium is, as its name would imply, crystallographically isometric. Synthesized material contains a certain mole percentage (10-15%) of metal oxide stabilizer, typically Yttrium oxide. In colored CZ other oxides are added to produce the colors. The stabilizer is required for cubic structure formation; otherwise zirconium oxide would form monoclinic crystals during synthesis. The amount and the type of stabilizer used depend on the recipes of individual manufacturers. Therefore the physical and optical properties of synthesized CZ vary, all values being ranges.

PROPERTIES:

Cubic Zirconium is a dense substance with the following properties:

:     CONCHOIDAL

Cubic zirconium is considered brittle. Under shortwave UV cubic zirconium typically luminesces a yellow, greenish yellow or "beige." Under long wave UV the effect is greatly diminished, with sometimes a whitish glow being seen. Colored stones may show a strong, complex rare earth absorption spectrum. Cubic Zirconium is an excellent thermal insulator.

We are offering many different qualities in Cubic Zirconia White Gemstones A, AA, AAA, Machine Cut (4A and 5A) and Heart & Arrow Quality Gemstones.



A QUALITY CZ WHITE DIAMONDS:

Cubic Zirconia White AAA Quality has available in different grades A, AA and AAA. There are 58 facets in all the stones but we are making the difference based on polishing and the quality of cut.

1. CZ White A Quality - "AAA" Low Quality (Polish and Cut)
2. CZ White AA Quality - "AAA" Medium Quality (Polish and Cut)
3. CZ White AAA Quality - "AAA" Best Quality (Polish and Cut)

HIGHLY RECOMMENDED - CZ AAA Quality Stones are best choice for which using to set in gold and silver Jewelries, because AAA quality stones cutting and eye looking close to Diamonds at affordable prices.


We can provide Cubic Zirconia White AA and AAA Quality Gemstones with any shapes/cuts and size

Cubic Zirconia White AAAAA (MACHINE CUT) Quality Gemstones:

Cubic Zirconia White AAAAA (MACHINE CUT) Quality has different grades 4A and 5A. There are 58 facets in all the stones same like AA Quality but we are using high quality white rough to make this AAAA (Machine Cut) Quality Stones.

1. CZ White 4A Quality - "5A" Medium Quality (Polish and Cut)
2. CZ White 5A Quality - "5A" BEST Quality (Polish and Cut)


We can provide Cubic Zirconia White 4A and 5A Quality Gemstones with any shapes/cuts and size

Cubic Zirconia White Heart and Arrow Quality Gemstones

Cubic Zirconia White Heart and Arrow Quality has different grades A, AA and AAA. There are 8 Hearts and 8 Arrows perfectly in all the stones same, But we are determine the quality based on Polishing and Cut Quality 

Perfectly formed Hearts and Arrows patterns with eight hearts AND eight arrows (above, left) are only found in diamonds that meet the American Gem Society Laboratories' "0" Ideal Cut specifications. The IdealScope was invented by Kazumi Okuda in the 1970's, and its later incarnation, the "FireScope," was invented by Ken Shigetomi and Kazumi Okuda in 1984. The first official H & A "EightStar" diamond was cut in 1985 by Kioyishi Higuchi for Japanese businessman and FireScope manufacturer, Takanori Tamura.

1. CZ White H&A A Quality - "H&A (AAA)" Low Quality (Polish and Cut)
2. CZ White H&A AA Quality - "H&A (AAA)" Medium Quality (Polish and Cut)
2. CZ White H&A AAA Quality - "H&A (AAA)" BEST Quality (Polish and Cut)
