What is optical crystal?
Optical /Optic Crystal, as clear and as flawless as used in binoculars and camera lenses, represents the ultimate expression of excellence.

Why does Crystal make a sound?
When you run your finger around the glass, this gives energy to the molecules in the glass making them vibrate. When individual molecules in the glass vibrate it makes the whole glass vibrate. This vibration then transfers to the sir molecules and that is what makes up the sound waves that you hear.
