Heating can convert blue material toward golden-brown; dye and imitation glass occur.

Observation guide

What to check

Move under one light and inspect edges for concentrated dye or uniform manufactured fibers.

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

Mild soap and water. Avoid high heat if preserving blue color.

Responsible buying

Ethics and sourcing

Sellers should distinguish natural blue material from dyed or heat-altered products.
