Swarovski Crystal
Swarovski Crystal isn’t a gemstone or even a crystal it’s a form of glass
that’s made at high temperatures by melting silicon oxide powders with lead
to form what is known as lead crystal. The exact process is one that’s
patented by Swarovski but it has approximately 32% lead content to increase
the crystals refraction index to resemble that of a diamond.
