Transparency

Transparency describes how well light passes through a mineral sample. There are three degrees of transparency: transparent, translucent, and opaque. You can see objects through a transparent mineral. You can see light, but no objects through a translucent mineral. You can't see anything through an opaque mineral.

The sample of beryl shown here is nearly transparent.
