Cubic Zirconia Color Change Gems
Cubic zirconia (CZ) color change gems are beautiful alternative stones to 100% carbon diamonds. These stones are preferred due to their durability, visual likeness to real diamonds, low cost, and smooth shaping potential.
These gems can appear in at least two color shades depending on the light you put them under. Many jewelers prefer color change gems as they provide buyers with the right glitter and hue shade they want from luxury gemstones. Its like you are getting 2 gems in 1.
There’s so much more about CZ color change gems you need to know. That’s why this article provides detailed information about CZ color gemstones, their history, uses, and much more.
History of Cubic Zirconia Color Change Gems
Baddeleyite is the first form of CZ crystals ever discovered in 1892. The rare form of this crystal gave way to discoveries about CZ gems of different cuts and features from the 1920s.
Russian chemists will go on to perfect this procedure and mass-create CZ crystals with different features in the 1970s.
How are Cubic Zirconia Color Change Gems Made?
Skull-melting is the most popular method to create color change CZ gems. Zirconium oxide and stabilizers like magnesium or calcium go under intense heating to form crystals.
During the process, these color change gems might absorb one or more elements that appear different under fluorescent lighting and sunlight. These elements produce the different colors visible to naked eyes under different lights. Each color assumes the crystal’s refractive index in suitable lights and becomes recessive under incompatible lighting.
Uses of Cubic Zirconia Color Change Gems
Cubic zirconia color change gems are ideal as:
- Gemstones,
- Fittings on window pieces
- Centerpieces in luxury lighting, and
- Adornments on musical instruments, decorative vases, etc.
Jewelers prefer CZ color change gems for these uses and much more since it has low shock potential, friction with high resistance to chemical reactions or heat.

Cubic zirconia needs regular maintenance to restore its brilliance and shine. How a CZ crystal receives maintenance largely depends on its setting base, mount design and other factors.
You can clean CZ gemstones with similar techniques used to maintain real diamonds. Some of the most effective methods are:
- Polishing with a dry cloth,
- Cleaning with loosely-concentrated soap solution (water to soap ratio at 4:1 or more),
- Storing in an airtight container free from humidity, and
- Soaking in a vinegar and baking soda solution for 10mins before cleaning and storage
