Real vs Fake Amethyst
Worried your Amethyst might be fake? Here’s how Amethyst is imitated and the quick checks that tell the real thing apart — no lab needed for a first pass.
How Amethyst is faked
The usual imitations: dyed quartz/glass, and synthetic (lab-grown) amethyst sold as natural.
Real vs fake Amethyst at a glance
| Genuine Amethyst | Imitation | |
|---|---|---|
| Colour zoning | Uneven, angular bands | Flat, uniform (dyed) |
| Bubbles | None | Round bubbles (glass) |
| Feel | Cool, scratches glass | Glass warms fast, softer |
How to tell real Amethyst
- Natural amethyst usually shows uneven colour zoning (angular bands or darker tips); dyed stones and glass are flatly uniform.
- Glass imitations contain round bubbles and warm up fast in the hand; quartz (real or synthetic) stays cool.
- Lab-grown amethyst is real quartz and hard to separate by eye — only its near-flawless clarity and a lab hint at it; it should be disclosed.

Frequently asked questions
Is my amethyst real or glass?
Real amethyst is quartz: cool to the touch, hard (scratches glass), and usually shows uneven colour zoning. Glass fakes have round bubbles, feel warmer and are softer. Lab-grown amethyst is genuine quartz but should be sold as "created".
What is Amethyst worth?
Real Amethyst and its imitations differ a lot in value — see the value guide. Imitations (glass, dyed or reconstituted material) are worth a small fraction of the genuine stone.
