Lookalikes

Commonly confused with

Dyed agate, red glass, jasper, fire opal.

Market context

Treatments and imitations

Heating has a long history and can deepen color; dye also occurs.

Observation guide

What to check

Backlight for translucency and inspect drill holes or fractures for dye concentration.

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 and acids around dyed or repaired material.

Responsible buying

Ethics and sourcing

Traditional heat is not automatically deceptive; undisclosed treatment is the issue.
