Strontium Titanate Gemstone & Information | Gemopedia by JTV | Gemopedia™
As its name implies, strontium titanate is an oxide combination of strontium and titanium that was originally created as a diamond simulant. However, strontium titanate gems are easy to distinguish from diamonds, as their high dispersion and considerably lower hardness are dead giveaways. 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. However, there was one problem with the crystals--they were SO small that they couldn't be cut into gems!
