A.D. is made of rocks.

Rocks are made of minerals, they form our natural environment -  the mountains, forests and riverbeds.

A crystal is a mineral that consists of matter. It is formed by a regular

repetitious pattern of atoms, molecules or ions that recur over and over throughout the entire material. This repetitive nature allows crystals to grow in strange and

interesting forms, naturally.
