Common clear quartz fakes & look-alikes

• Glass spheres & points. Glass is often flawless-clear with rounded bubbles and a slightly warm feel. Natural quartz usually has some inclusions, veils, or growth lines and feels cool and heavy.
• Molded glass 'points'. Look for mold seams and identical, repeated shapes — natural quartz points vary and show real crystal faces.
• Leaded 'crystal' glass. A very heavy, very bright 'crystal' ball is usually leaded glass, not quartz.

Simple at-home tests

1. 1Scratch test. Quartz (Mohs 7) scratches glass; glass will not scratch quartz. A quartz point should leave a mark on a glass bottle.
2. 2Temperature. Quartz feels distinctly cool and warms slowly; glass sits closer to room temperature and warms fast in the hand.
3. 3Bubbles vs inclusions. Round, suspended bubbles mean glass. Angular inclusions, phantoms, or internal fractures mean natural quartz.

At-home tests are indicative, not definitive — for valuable pieces, get a professional gemologist's opinion.

The bottom line

If it scratches glass, feels cold and heavy, and has natural inclusions rather than round bubbles, it's genuine clear quartz. Flawless clarity with bubbles and warmth means glass.

FAQ

How can I tell if my clear quartz is real?

If it scratches glass, feels cold and heavy, and has natural inclusions rather than round bubbles, it's genuine clear quartz. Flawless clarity with bubbles and warmth means glass.

Is clear quartz valuable?

Usually modestly — it's very common — but large clean points, spheres, and specimens with rare inclusions can be worth hundreds.

How do I know it's real quartz, not glass?

Quartz scratches glass, feels cool/heavy, and shows natural inclusions; glass feels warm and may have rounded bubbles.
