Cubic Zirconium {CZ} was discovered in its natural state in 1937
by two German mineralogists, von Stackelberg and Chudoba.
It was in a highly metamict zircon given to them by one
B.W. Anderson. The zircon contained tiny crystals that
were determined to be the cubic form of zirconium oxide by
X-ray diffraction. The two mineralogists thought so little
of their discovery that they did not even give it a name,
which is why it is still known by it's scientific name,
CUBIC ZIRCONIUM.
It was not until the 1970s, however, that Soviet scientists
learned how to grow the crystals in the laboratory.
In 1977, it was first marketed under the trade name Djevalite.
But CZ really took off in the 1980's when Swarovski and Co.,
a world-renowned Austrian producer of leaded crystal,
began producing Cubic Zirconia for mass consumption.
A Cubic Zirconium is made through a complicated process
and is made up of zirconium oxide and yttrium oxide.
Together the two chemicals create a beautiful, radiant crystal.
It takes around 2,760° C to melt the two chemicals together and
the most important process is the cooling. The chemicals must be
carefully cooled in order to create high quality flawless crystals.
The Cubic Zirconium is a beautiful substitute for those who cannot
afford a natural diamond or simply choose not to spend that much.
Quality of 5A and better Cubic Zirconia look as good
and in many cases, better than most natural diamonds.
According to some, diamonds are actually quite worthless.
It is only the brilliant marketing strategy by De Beers,
which has resulted in them becoming so expensive.
