Cubic Zirconia, Crystal, Moissanite and Lab-Grown Diamond: What's the Difference?

Sparkling stones in jewelry aren't all the same. The most common in silver jewelry are cubic zirconia and crystal, and in higher categories moissanite and lab-grown diamond. Here's a simple guide to the differences.


Cubic Zirconia

A clear lab-made stone that sparkles like a diamond, reasonably hard and available in every color and cut. That's why it's the most widely used stone in everyday silver jewelry and sets.


Crystal

High-quality glass containing lead, which gives it strong shine and reflections. It's softer than cubic zirconia, so it suits pieces with little friction such as earrings and pendants.


Moissanite

A stone very close to diamond in hardness, with a fiery, multi-colored sparkle. It costs much more than cubic zirconia and less than diamond.


Lab-Grown Diamond

Real diamond in composition and hardness, but made in a lab instead of mined. It costs less than natural diamond and more than the other options.


Quick Comparison

  • Brilliance: moissanite and diamond highest, then cubic zirconia, then crystal.
  • Hardness: diamond, then moissanite, then cubic zirconia, then crystal.
  • Price: crystal and cubic zirconia most affordable, then moissanite, then lab-grown diamond.

Caring for Stone-Set Pieces

  • Clean them with a soft brush and warm water, without long soaking.
  • Keep them away from perfume and creams so the stones keep their shine.
  • Store them separately, as harder stones can scratch others.
