Counterfeiting has become widespread due to the popularity and high price of these stones. Let's see how to protect yourself.

02The six characteristics of fakes

1 — Color

Fake moldavites can have colors ranging from bottle green to unlikely shades (yellow, blue, red). Authentic ones only exist in shades of green (see the color guide); in natural light, thicker ones may appear almost black.

2 — Sculpture

• Fakes have a uniform, overly smooth and regular surface.
• Authentic ones feature an intricate and abstract sculpture, impossible to replicate faithfully.

3 — Transparency

• Fakes often appear more transparent, similar to colored glass.
• Authentic ones contain minerals and metals (like iron) that make them less transparent.

4 — Surface luster

• Fakes often have a shiny and brilliant surface, or are completely opaque.
• Authentic ones can have a natural luster, but never exaggerated.

5 — Uniqueness

Every moldavite is as unique as a fingerprint or a snowflake. If you see the same image used for multiple items or listings, it's definitely a fake. Only buy when you see photos of the exact piece, from multiple angles (at least front and back) and ideally with a backlit one. It helps to understand how the shapes are formed.

6 — Weight

The average weight of a moldavite is about 4 grams, similar to some coins. Specimens over 20g are rare and cost hundreds of euros; over 40g they can reach thousands.

• A 2€ coin weighs 8.50g (more than twice the average moldavite); a 1€ coin 7.50g; a 50 cent coin 7.80g; a 20 cent coin 5.74g; a 10 cent coin 4.10g (very close to the average weight).
• Moldavites over 30g are extremely rare online: maximum caution.
• If the weight is in carats and not in grams, check: 4 carats = 0.8g. Be careful not to overpay for minimal quantities.

03Six warning signs

1 — Country of origin

Countries known for fake moldavites: China, India, Thailand, Vietnam, Hong Kong. Avoid purchases shipped from these countries, especially online.

2 — Price

If the price seems too good to be true, it's probably a scam. As a guide, an authentic moldavite costs: 1g about 28–35€; 10g about 280–350€; 20g about 930–1,240€; 30g about 1,950–2,300€; 40g about 3,350–4,100€. A 10–15g moldavite cannot cost 35 pounds.

3 — Extraction location

99% of authentic moldavites come from the Czech Republic. Those from other countries are extremely rare and almost always fake. See where moldavite is found.

4 — Non-specific images

Some sellers use photos of authentic moldavites to attract buyers, but send a fake or different piece (the bait and switch tactic). Only buy if you see the exact piece you will receive. Avoid listings with generic photos or "random selection": a wide range (e.g., 4–8 carats) allows the seller to ship stones smaller than the value paid.

5 — Auction Sales

Online auctions are often fertile ground for fakes: some sellers use fictitious accounts to artificially inflate prices.

6 — High-Risk Sites

Completely avoid AliExpress and Alibaba. On eBay and Etsy, proceed with extreme caution.

04Fake Faceted or Polished Moldavites

1 — Lechatelierite

Authentic ones show subtle wavy lines of lechatelierite, melted quartz formed during impact.

2 — Bubbles

Authentic ones contain tiny bubbles smaller than 1 mm, visible only with a loupe or macro lens.

05Jewelry with Fake Moldavites

1 — Missing a Feature or Sign

Apply all the features seen above. Moldavite jewelry is expensive because polishing and faceting require time, skill, and generate waste. If it's difficult to tell if the stone is authentic, ask for detailed close-up photos and information on weight, origin, and craftsmanship. Check that the seller has positive reviews confirming authenticity.

2 — The Price

Price is a key indicator. A single 10mm moldavite bead costs approximately €55–75; an authentic bead bracelet can be worth €1,100–€1,300. If you find "moldavite" at ridiculously low prices, it is almost certainly common green glass.
