Tourmaline

A complex silicate mineral,
known for its wide range of colors.

Tourmaline can appear in green, pink, black, blue,
and sometimes multiple colors within a single crystal,
depending on the trace elements present during formation.

In some cases, a single crystal can show distinct color zones,
formed as conditions changed over time.

Its structure tends to grow in elongated, column-like crystals,
often with natural striations along the surface.

Rather than a single identity,
tourmaline is defined by variation —
each piece reflecting the environment in which it formed.

It has often been associated with balance and protection.
