合成キュービックジルコニア (合成キュービックジルコニア) 略称CZ, 最初に登場したのは 1976, 旧ソ連によって人工的に合成された, したがって、次の別名があります。 "ソビエトダイヤモンド", 今ではとして知られています "ロシアンダイヤモンド". この種の別名は誤解を招きやすいため、, 標準名としては使用できません. 名前 "ダイヤモンド" is used because its visual effect is very similar to that of diamonds. It even has "火の色", which is often used as a substitute for diamonds.
The synthetic method of synthesizing cubic zirconia is the cold crucible method, and the current output is very high because it is not only beautiful in appearance, but also inexpensive. Taking the famous synthetic cubic zirconia from Swarovski Austria as an example, 100 1ct size finished synthetic cubic zirconia gemstones cost only $20.
If different metal oxides are added to the synthetic cubic zirconia raw material, synthetic cubic zirconium crystals of different colors can be obtained. 例えば, cerium: 黄色, オレンジ, 赤; クロム: 緑; neodymium: 紫; erbium: ピンク; チタン: golden brown.
近年では, some manufacturers have also used different methods to improve their products. The most common is to add a layer of diamond-like carbon (DLC) to the surface of synthetic cubic zirconia by steam condensation. The resulting product is harder than ordinary synthetic cubic zirconia and looks more like diamonds. Another method is to spray a layer of metal oxide on the surface in a vacuum to make it appear blooming, but unlike the diamond-like carbon plating, this processing layer can be worn.
Synthetic cubic zirconia is often used as an imitation of diamonds because of its appearance similar to diamonds and its low price. It is also used to imitate high-end gems such as rubies and sapphires. The quality evaluation is based on color, transparency and clarity, and the main requirements are pure color. 高い透明性, less internal impurities and no cracks.
