Show sample as: 72-frame QuickTime VR or 360-frame QuickTime movie loop.    My periodic table poster is now available! Strontium Titanate fake diamond. Before the widespread use of cubic zirconia as fake diamond, strontium titanate was more popular. It is, however, much softer than diamond, and much more expensive that cubic zirconia. I like it because it's a pretty use of strontium. Source: Theodore Gray Contributor: Theodore Gray Acquired: 11 March, 2009 Text Updated: 12 March, 2009 Price: $20 Size: 0.25" Composition: SrTiO3
