What is this stone?
Strontium Titanate quickly gained popularity in the industry for its clarity and was found to be the closest thing to diamond in appearance, though it has nearly twice the fire of a diamond. The major competition for diamond simulants at the time was Titania which is a simulated rutile compound.
However, its popularity, like most, was short-lived when the stone was overshadowed by the newly created CZ. Sadly, Strontium Titanate faded into the background but occasionally reared its pretty head in pendants and earrings.
