The fascination of crystals…The fascination of

crystals…They spark and attract with their beautiful light.

They come with interesting shapes and colors

Collecting them can be an exciting and challenging experience.

What makes up a crystal??

What makes up a crystal??

Atoms are building blocks of crystals.

Even the smallest crystal (salt)is made up of millions of atoms.

For every type of crystal there is a different combination of atoms.

Salt for example is composed of sodium and chlorine.
