From ages, gemstones are cut and polished for self-decoration. There are mainly three types of gemstones produced all over the world- natural gemstones, lab created gemstones and simulants. Over the last couple of years, enormous growth and demand has been noted in the market of lab created loose cubic zirconia gemstones.
As a diamond simulant, the trend of buying lab created cz gemstones is simply outstanding. This high quality and cheap gemstones can be cut into a range of bead and shapes. Most faceted gem shapes follow those for precious stones (like diamond), with a pavilion, crown, girdle and table. The edges may be slightly rounded in comparison to a diamond. In recent years, manufacturers have sought ways of distinguishing their product by supposedly “improving” cubic zirconia.
Coating finished CZs in a film of diamond-like carbon (DLC) or Amorphous Diamond is one such innovation—a process using chemical vapor deposition. The resultant material is purportedly harder, more lustrous and more like diamond overall. When you shop for loose cubic zirconia jewelry, the online store will probably list a karat weight but may call it a ‘diamond equivalent,’ to help you understand how the (heavier) CZ would compare to a diamond of the same visual size.
Cubic zirconia is crystallographically isometric, an important attribute of a would-be diamond simulant. During synthesis, zirconium oxide would naturally form monoclinic crystals, its stable form under normal atmospheric conditions.
Cubic zirconia is not real and is not a diamond, though it is difficult for the naked eye to tell the difference between a cubic zirconia and a diamond. It is a stone that is as brilliant as a diamond but much more affordable. A single mass of cubic zirconia is relatively heavier compared to a diamond even if both are similar in size. Nevertheless, diamonds are harder compared to cubic zirconia.
