Strontium Titanate is a synthetic gemstone, produced through the combination of two metals: strontium and titanium. It is synthesized through a process known as flame-fusion, where the two metals are heated with a brilliant, hot flame and treated with a mixture of chemicals to produce this marvelous gem.

Purely synthesized strontium Titanate is colorless in appearance, and when it is faceted it creates a brilliant, intense fire, also known as dispersion. This fire is four times greater than that which is seen in diamonds of a similar cut! The inclusion of rare earth metals, through a process known as doping, can produce many varieties of color within this gem, such as red and yellow. As a synthetic gemstone, strontium Titanate is usually free of inclusions, however, on occasion, a bubble can be seen within the stone.

Strontium Titanate is almost always faceted, as it's primarily used as a simulated diamond. It is commonly available in all calibrated fancy cuts seen in the market today. As a simulated diamond, the stone can be distinguished from diamond by its lower hardness on the Mohs scale, and its dispersion of light.
