Observation guide

What to check

Use directional light to see irregular internal plates; inspect for bubbles and even glitter.

Use visual checks to ask better questions, not to replace qualified testing when identity, treatment, value, or origin is consequential.

Practical handling

Care and safety

Avoid steam and ultrasonic cleaning; protect cleavage edges.

Responsible buying

Ethics and sourcing

Mine-specific origin and copper-color claims require documentation; support transparent small-scale producers.
