For the most part, this jewel fell into obscurity when the hugely popular cubic zirconia (CZ) entered the market in the 1970's. While strontium titanate was originally believed to only be available via laboratory creation, it was discovered in natural form in the 1980's in Siberia and named tausonite in honor of a Russian geochemist.
