How Much Is Moldavite Worth?

Also known as Vltavín

Moldavite — a bottle-green tektite glass formed by a meteorite impact about 15 million years ago and found only in a small strewn field around the Czech Republic — is genuinely scarce and valuable, and the market is flooded with fakes. Authentic moldavite runs roughly $8–$20 per gram for common grade and $30–$100+ per gram for museum-grade pieces with fine 'fern-like' natural sculpting; faceted gems cost more. Because demand exploded, most cheap 'moldavite' sold online is mass-produced green bottle glass from China or India. Value depends on authenticity first, then weight, surface texture (natural etched sculpting vs smooth glass), translucency, and color. A certificate of authenticity from a reputable Czech source matters more here than for almost any other stone.

What drives moldavite value

  • Authenticity. The #1 issue — most cheap moldavite is glass. A COA protects value.
  • Surface texture. Natural etched 'wormy' sculpting beats smooth glassy surfaces.
  • Weight. Priced per gram; larger genuine pieces are scarcer.
  • Translucency & color. Even forest-green with internal swirls is desirable.

Is your moldavite real?

Most cheap moldavite is green glass. Genuine moldavite has a matte, etched, irregular surface (not glossy), internal bubbles and swirls (lechatelierite), and an organic shape. Glossy, smooth, mold-seamed, or suspiciously cheap pieces are fakes.
