Cubic zirconia was discovered
by two German scientists in 1937. It wasn't until the 1970's, however, that
Russian scientists learned how to grow the crystals in the laboratory. Russian
cubic zirconia is still considered to be the highest quality. Cubic zirconia did
not become popular until the 1980's when Swarovski & Co. began making them in
mass quantities.
A cubic zirconia is made through a complicated process and is a made up of
zirconium oxide and yttrium oxide. Together the two chemicals create a
beautiful, radiant crystal. It takes almost 5,000 degrees Fahrenheit to melt the
two chemicals together and the most important process is cooling. The chemicals
must be carefully cooled in order to create flawless crystals.
To the untrained eye, cubic zirconia looks identical to a good quality diamond,
but CZ has slightly less brilliance or sparkle than a diamond and more fire or
flashes of color. The overall effect is so similar that it can even fool a
trained gemologist on occasion. One great difference between cubic zirconia and
diamond is weight; CZ is about 75% heavier than diamond. A piece of CZ the same
size as a one carat diamond weighs about 1.75 carats. Cubic Zirconia is also
flawless, whereas diamond usually contains impurities and inclusions.
CARING FOR REGULAR (NOT MYSTIC) CZ JEWELRY:
(non mystic) cubic zirconia can be cleaned with any conventional jewelry cleaner
or detergent. With such a high hardness and durability (8.5 on Moh's Scale of
Hardness), you can use a brush to clean off dirt or oil also. Ultra sonic
jewelry cleaners may also be used on CZ and will not damage the stone. However,
when using soaps or detergents to clean CZ, one should wipe the jewelry dry
thoroughly to avoid residue from the soap leaving a film that will dull the
brilliance of the stone. Cubic Zirconia should be cleaned frequently to remove
oils from skin that also dull the brilliance of the gem.
Mystic CZ Jewelry (Mystic Ice):
Mystic CZ are done with the
same process as the Mystic Topaz and by the same laboratory . It is a lab
created cubic zirconia enhanced with a US patented coating technology. A thin
film is applied to the stone. This process is called “physical vapor
deposition”; it uses various minerals. No harsh chemicals or radiation is used.
This process produces a kaleidoscope of colors.
Because cubic zirconia have "fire" that topaz lacks the results with cz
gemstones are even more spectacular visually than with topaz. Mystic fire topaz
has rich deep colors while with mystic ice cz jewelry there is more brilliance,
sparkle, and fire, as well as a greater rainbow effect. Unless you specifically
love topaz, you will not be disappointed in your
mystic
ice cz jewelry.
The coating is durable and hard and will last a lifetime provided that it is not
exposed to any abrasive, acids, high heat or immersed in an ultrasonic cleaner.
To clean it, simply use mild soap and water or windex.
