Is Your Moldavite Real or Fake?
How to tell genuine moldavite from imitations
Moldavite is the poster child for fakes: genuine material is restricted to one Czech location, so the flood of cheap 'moldavite' online is overwhelmingly molded green glass. Telling them apart is mostly about surface texture and provenance.

Common moldavite fakes & look-alikes
- Molded green glass. Glossy, smooth surfaces, mold seams, and uniform round bubbles. Real moldavite has a matte, etched, wormy texture — never factory-smooth.
- Too-cheap / bulk lots. Bags of identical 'moldavite' or prices far below ~$8/g are a near-certain tell of glass.
Simple at-home tests
- 1Surface under a loupe. Natural moldavite shows etched, fern-like or 'wormy' sculpting and pitting. Smooth, glassy, flowing surfaces indicate molded glass.
- 2Bubbles & inclusions. Genuine pieces have irregular elongated bubbles and lechatelierite (glassy swirls). Perfectly round, evenly spaced bubbles suggest manufactured glass.
- 3Provenance / COA. Buy only with a certificate from a reputable Czech dealer. For moldavite, source and paperwork are part of authentication.
At-home tests are indicative, not definitive — for valuable pieces, get a professional gemologist's opinion.
The bottom line
Matte etched 'wormy' texture, irregular bubbles, organic shape, and a credible Czech COA point to genuine moldavite. Glossy + seamed + dirt-cheap = green glass.
