Diamond Coated Cubic Zirconia
Diamond Coated Cubic Zirconia
Diamond coated cubic zirconia is a crystal mix with a zirconium dioxide (ZrO2) interior and real or synthetic diamond veneering. The interior synthesized material is usually hard, colorless and more malleable than its diamond exterior.
Diamond coated cubic zirconia is not the same as zirconium silicate or cubic zirconium, even if all three elements share one main mineral.
Diamond-veneered cubic zirconia is a preferred alternative for buyers and jewelers looking for low-cost gemstones on earrings, watches, necklaces, and other jewelry pieces. Cubic zirconia is also an option for veneering since it has several likenesses with real diamonds.
In this article, we’ll look at essential details of diamond coated cubic zirconia like its chemical composition, how to make it, its uses, history, and other vital information.
History of Diamond Coated Cubic Zirconia
Scientists discovered the natural form of cubic zirconia (CZ) in 1892; however, it will take several years before chemists could synthesize CZ crystals. Chemists were able to stabilize the mineral and create a mass production method to meet growing demand.
How to Make Diamond Coated Cubic Zirconia
Cubic zirconia is easy to mass-produce through the skull-melting method, Its diamond veneering might be done with real diamonds or lab-made knockoffs.
First, chemists add zirconium oxide with a stabilizer into a crucible. Calcium and magnesium are common stabilizers used to create zirconia crystals.
The entire mix is heated to ~4,900ºF and left to cool while its crystals form internal isotropic structures. Experts cut, polish, and prepare the cubic zirconia crystals for veneering.
Plasma ion deposition is the choice method to deposit real diamonds in a matrix on CZ crystals. The method deposits diamond nanocrystals no larger than 60nm uniformly across the base gemstone.
Uses of Diamond Coated Cubic Zirconia
Diamond coated cubic zirconia crystals are ideal as jewelry pieces and can work as fitting on luxury glasswork. Veneered crystals are usually expensive and difficult to purchase for use as filters or substrate.

Maintenance Tips for Diamond Coated Cubic Zirconia
Diamond coated cubic zirconia could lose its outer shine due to poor storage or rough handling. These crystals should receive curated maintenance that matches its setting, design, and holding metal.
Diamond coated cubic zirconia crystals are easy to maintain and you can adopt the same cleaning method used on 100% carbon gemstones like:
Liquid soap
Add soap to water at a minimum ratio of four to one. Next, rub the surface of your diamond coated CZ crystal with this soap solution to remove visible dirt and grime.
Clean the gem with a dry cloth, rinse it in lukewarm water, and allow to air dry. Make sure you use a dry cloth made from smooth material to avoid leaving scratches on your diamond-veneered crystals.
Polishing
Soft cotton polishing cloths are ideal to maintain diamond coated CZ gemstones. You first need to rub the gem gently before storing in a special case to prevent dirt and grime from settling on the crystal’s surface.
You can seek advice from professional jewelers to identify the best cleaning method for your diamond coated CZ crystals. Some stains might be too tough for liquid soap or polishing to remove.
