👉 A drumloidal is a type of crystal that is composed entirely of aluminum. It is often used in the production of decorative and ornamental items such as jewelry, sculptures, and decorations.

The outer layer of aluminum is usually coated with a transparent material like silver or gold, while the inner layer is made of the same type of aluminum as the outer layer
