Moldavite Value: Price Per Gram and How to Spot a Fake
Moldavite value: about $20–$80 per gram for most genuine pieces; $70–$500+ for top Besednice pieces
Moldavite is a green natural glass thrown out by a meteorite impact in southern Germany about 14.8 million years ago, and it is found mainly in the Czech Republic. Ordinary to good raw pieces sell for about $20–$80 a gram today, and highly sculpted Besednice pieces for $70 to over $400 a gram. Prices roughly tripled during the 2021 TikTok boom and have stayed high. Those prices attract fakes made of green glass, so check a piece before you pay for it or price it.

Moldavite Prices by Grade (2026)
Asking prices per gram from moldavite and meteorite dealers, September 2026.
| Grade | Details | Price per gram |
|---|---|---|
| Standard raw (A grade) | Undamaged, ordinary sculpture; median sale prices at a large Czech dealer | Price per gram: $39–$54 |
| Small raw pieces from US dealers | Individuals of about 1–15 g | Price per gram: $20–$81 |
| Better sculpture (A+ to A++) | Deeper etching, better shine | Price per gram: $46–$100 |
| Besednice 'hedgehogs' | Spiny pieces from a mined-out Czech locality; top larger pieces cost the most | Price per gram: $68–$137 small; up to about $500 |
| 'Angel chime' | A seller's term for thin plates that ring when tapped; no grading standard | Price per gram: $70–$132 (one dealer) |
| Czech prices in 2020, before the boom | For comparison | Price per gram: About $4–$8 |
Most listings at one large Czech dealer carry about a 31% 'sale' discount, so compare actual sale prices, not the 'regular' price. Price per gram rises with size: 20 g pieces cost 50–100% more per gram than small ones.
What Makes a Moldavite Worth More
The factors buyers and dealers actually price on.
Weight
Price per gram rises with size. Typical pieces weigh about 4–8 g, and pieces over 50 g are very rare.
Surface sculpture
Deep, complex etching, made by acidic groundwater over millions of years, is the most prized look.
Condition
Undamaged pieces are worth more; most chips and abrasion happen during mining.
Shape
Rare original shapes such as drops, discs and dumbbells cost much more, up to 20 times a regular piece of the same size.
Locality
Besednice pieces carry a big premium because the deposit is mined out, which is also why fakes and Chlum pieces get sold as 'Besednice'.
Color and clarity
A more intense, clear green costs more.
Documentation
Seller certificates add little because they are easy to fake. An independent gem lab report carries real weight.
How to Tell if Moldavite Is Real
Moldavite and man-made glass are both glass, so no single home test proves it. Look for several of these signs together, and use a gem lab for valuable pieces.
- 1
Worm-like inclusions
Under a 10× loupe with light behind the stone, look for thin, worm- or wire-shaped inclusions of pure silica glass (lechatelierite). They are the most telling sign, though not every piece shows them.
- 2
Many stretched bubbles
Real moldavite usually has lots of gas bubbles, often elongated. Bubbles alone prove nothing, because glass has them too; one fake tested by GIA had very few.
- 3
Chaotic flow lines
Natural swirls look irregular, like heat haze. Straight, evenly spaced lines suggest an acid-etched fake.
- 4
Natural sculpture
Real pieces have varied, etched surfaces. Smooth molded edges, drilled ridges and many identical shapes point to molded glass.
- 5
Color
Genuine moldavite is olive, bottle green or brownish green. Blue, red or other colors sold as moldavite are fake.
- 6
Clarity, size and price
Very clear pieces with no visible bubbles, faceted stones over about 2 carats, and large pieces at low prices are red flags. A faceted 'moldavite' bought online for about $30 turned out to be glass.
- 7
Origin
Moldavite only comes from central Europe, mostly the Czech Republic. 'African moldavite' is manufactured glass.
- 8
Lab tests
A gem lab can measure specific gravity (about 2.36 for moldavite; one fake measured 2.45), refractive index and chemistry to settle it.
Common look-alikes
Green bottle and factory glass
The most common fake, sometimes acid-etched to imitate natural sculpture.
Molded replicas
Cast from real pieces, so several identical shapes turn up.
'African moldavite'
A trade name for manufactured glass. It tends to look clearer than real moldavite, with fewer inclusions.
Other impact glass
Libyan Desert Glass is a paler yellowish green. 'Saffordite' and 'Cintamani' sold online are often fake.

Collecting Rules to Know
- In the Czech Republic, moldavite may be collected on fields with the landowner's permission. Digging without state permission is illegal, police patrol known sites, and repeat offenders face criminal charges.
- Moldavite is a tektite, a natural glass made by an impact, not a meteorite.
- Healing claims made about moldavite have no scientific evidence behind them.
How to Sell a Moldavite
- Weigh each piece to 0.01 g, give its dimensions and photograph the actual stone.
- State the locality honestly; only claim Besednice if you can document it.
- Get an independent gem lab report for faceted stones and high-value pieces rather than relying on a seller certificate.
- Established moldavite, tektite and mineral dealers are the usual buyers; open marketplaces are full of fakes.
- In the Ruby Glint app you can list moldavite in the marketplace and chat directly with buyers.

Moldavite Value Questions
Get answers to common questions about rock identification, rockhounding, and using our platform.
Most genuine raw moldavite sells for about $20–$80 a gram in 2026, depending on size, sculpture and condition. Highly sculpted 'investment' pieces and Besednice pieces cost about $70 to over $400 a gram.
No evidence of a crash. US retail prices roughly tripled from about $10–$16 a gram in 2020 to about $40–$50 by mid-2022, and dealers report they have stayed high and kept creeping up as deposits are mined out.
Under magnification, look for worm-like lechatelierite inclusions (the best sign), many elongated bubbles and chaotic flow lines. Warning signs are identical or perfectly smooth shapes, glass-like clarity, colors other than green or brownish green, big pieces at low prices and 'African moldavite' labels. For certainty, use a gem lab.
No. Man-made glass also has bubbles. Real moldavite usually has many, often stretched, plus lechatelierite inclusions.
From central Europe, mainly southern Bohemia and western Moravia in the Czech Republic, with smaller amounts in Germany and Austria. It formed about 14.8 million years ago when an impact created the Ries crater in southern Germany.
No. Certificates are issued by sellers and can be faked. An independent gem lab report is far stronger evidence.
