Cubic Zirconia History
This natural mineral was first discovered in the 19’th century. However the cubic zirconia as we know it as a gemstone doesn’t begin until many years later, during the 1970’s.
Natural Form of Zirconium Oxide
The natural form of cubic zirconia is zirconium oxide, which in itself is a bit yellowish in appearance. It was first discovered in 1892, but the mineral wasn’t considered to be of any value. It wasn’t until sometime in the early 1930s, that interest in the mineral really begun as scientists conducted experiments. During one of these experiments it was found that the mineral didn’t lose its strength when subjected to high heat, making it a refractory material. This was an important discovery and allowed inventors to use zirconium oxide in various applications, such as abrasives for ceramics, metal, and glass. Such as zirconia sanding belts.
