"CZ" translates to cubic zirconium (Aluminum Oxide).
There are many qualities of stones available that lay claim to
this name. Basically, the term refers to a lab grown cubic or
crystal that is the hardest natural mineral next to a diamond.
CZ's ranks in at an 8.5 hardness while the diamond reigns at
the perfect 10! The highest quality CZ offers such a close resemblance
to a diamond that it is hard to tell the difference. One difference
is that CZ's weigh about 75% more than a diamond of the same
size, so CZ's are measured in millimeters versus carats. Just
like diamonds, high quality, well cut stones, make a huge difference
in the final product. Amazingly, there are also fake CZ's!
Our CZ's are
made from Corundum. This mineral is found naturally growing as
a crystal. There are different qualities, of which many are opaque
and used for abrasives. But the clear crystals are kept for gems.
The crystals occur naturally as clear/colorless, pink, red, blue,
green, yellow and violet. These crystals are used for making
our range of CZ offerings. They are a great value!
Lab Grown CZ
Once again, Corundum is used, along with the natural chemical
structure of the stone to create stones that are high quality,
loupe clean and well cut. Our Sapphire, Ruby and Alexandrite
stones fall into this category. Our stones use the flux method
of growth. This method grows the highest quality and most expensive
Lab Grown CZs here...
These CZ beauties are also made from Corundum. They are high
quality, well cut and loupe clean. The process used to coat these
stones is the most sophisticated method to date. The stones are
coated with a thin film deposition surface enhancement; in other
words, a luster is added to the surface that is truly amazing.
Although permanent, the stone can't be re-cut or re-polished.
You can't fire these stones with Precious Metal Clay.

Tip: When ordering stones
be sure to order
for each stone unless you have another use in mind.
Important Note: Stone colors will vary in intensity
due to the natural material. We do our best to match pairs but
cannot control the stones. Colors shown on our web site are close
