The History of Cubic Zirconia
Since 1892 the yellowish, monoclinic mineral baddeleyite had been the only
natural form of cubic zirconia oxide known. Being of rare occurrence, it had little
economic importance.
Seven years later, German mineralogists M. V. Stackelberg and K. Chudoba
discovered naturally occurring cubic zirconia in the form of microscopic
grains.
Some of the earliest research into controlled single-crystal growth of cubic
zirconia occurred in 1960s France, much work being done by Y. Roulin and R.
Collongues.
Later, Soviet scientists under V. Osiko at the Lebedev Physical Institute in
Moscow perfected the cubic zirconia technique. Their breakthrough of cubic zirconia was published in 1973. By 1980 annual global
production of cubic zirconia had reached 50 million carats (10,000 kg).
