Product Description for Min 7.25ct 10x10mm Princess Cut Yellow Strontium Titanate-49S1001AP
Strontium titanate is a manmade gemstone that has great brilliance, making it a common diamond simulant. It has an extremely high refractive index and an optical dispersion that is greater than that of a diamond. It is not, however, as hard as a diamond; it only ranks 5 to 5.5 on the Mohs' hardness scale, making it relatively easy to damage. Care needs to be taken when working with these stones or wearing them in everyday "at risk" jewelry like rings and bracelets.
