A. What is the difference between Lannyte and a CZ?
Cz’s are much softer than Lannyte.  Cz’s will get milky, cloudy,
dull and scratch very easily in a very short amount of time.  Cz’s cannot be cleaned like Lannyte and natural diamonds.  Jewelry cleaner,amonia and household products will accelerate the breakdown of CZ.

You clean Lannyte just like your natural diamonds.  CZ’s tend to be cut and faceted by a machine because of their softness.  This produces very rounded stones, thus looking “fake”.   Lannyte, because of it’s hardness is cut by hand, just like natural diamonds, to exact specifications by master-diamond cutters.  Cz’s are very inexpensive and short lived, Remember, CZ's are imitations.
