Amethyst identifier · Experimental
Explore a purple crystal or gem.
Purple quartz is common and widely imitated. We look at colour distribution, crystal shape and matrix to suggest whether amethyst is a plausible match and what else could fit.

Questions
Is fading normal?
Some purple quartz can fade with prolonged strong light. Store specimens away from direct sun as a cautious default.
Can you tell synthetic amethyst?
Usually not from photos. Synthetic quartz can need laboratory examination.
Do you cover healing properties?
We keep cultural or spiritual traditions separate from scientific identification and make no health claims.
Should I scratch, heat or apply acid to test it?
No. Destructive home tests can damage the item and still mislead. Record what you can see and seek qualified testing when the answer matters.
