What are Crystals

Most gems begin their life as crystals of minerals (diamonds/sapphires) or as aggregates of crystals (malachite/jadeite).   Pearl and Amber are also known as gems even though they are noncrystalline.

A gem has many properties: it has depth, colour (or transparency), pattern and it remains beautiful regardless of age, wear or tear.  Gems are used to ward off evil, to heal and for beauty.
