Product Description for Apx 2.55ct 10mm Round Compass Card Cut Zandrite(Tm)
Zandrite is a type of synthetic glass that was created by a major glass manufacturer. A developing scientist realized that the new creation had gemstone marketing possibilities and started a movement that began a new gemstone trend. It has 100% color change abilities, which is why it was given the name "zandrite"--a play off of the very expensive natural gem alexandrite. Zandrite ranks a slightly fragile 5 on Mohs', the same as glass.
