Understanding Moldavite in Český Krumlov

Moldavite is a rare tektite found almost exclusively in the southern Bohemian region. It was created 15 million years ago when a meteorite struck the Earth. This impact melted local rocks and flung them across the landscape. Today, these green treasures are highly sought after by collectors and spiritual seekers alike.

In a popular destination like Český Krumlov, demand often exceeds the natural supply. This has led many souvenir shops to stock "African Moldavite" or "Chinese Moldavite," which are actually just glass. Authentic moldavite is a finite resource, making it relatively expensive. If you see a large, vibrant stone for a low price, it is almost certainly a fake.

The city is famous for its history and stunning architecture. You can see this beauty by visiting the State Castle and Chateau Český Krumlov during your stay. While exploring, you will notice dozens of shops selling green stones. Understanding the geological rarity of this gem helps you appreciate why fakes are so common.

How to Spot Fake Moldavite in Souvenir Shops

Follow this process to ensure you are buying a genuine piece of Czech history. This inspection should only take about five minutes per stone. Most honest sellers will allow you to examine the piece closely before purchasing.

1. Check the Color: Hold the stone up to natural light. Real moldavite has a mossy, olive, or forest green hue. If the stone looks like a bright emerald or a neon bottle, it is likely colored glass.
2. Look for Inclusions: Use a magnifying loupe to look inside. You should see tiny, elongated bubbles and wavy lines called Lechatelierite. Perfect clarity is a major red flag for fakes.
3. Analyze the Surface: Genuine stones have a deeply etched, matte texture known as "sculpting." Fakes often look too smooth or have a shiny, wet appearance like they were molded in a factory.
4. Request Documentation: Ask the seller for a certificate of authenticity. Ensure the certificate lists the specific locality where the stone was mined in the Czech Republic.

A common mistake is assuming that a high price guarantees authenticity. Some dishonest shops mark up glass pieces to trick tourists into thinking they are buying the real thing. Always rely on your visual inspection rather than the price tag alone. If you are unsure, it is better to walk away and visit another shop.

• Bright Flashlight: Use this to shine light through the stone to check its internal structure.
• Price Knowledge: Expect to pay at least $20-$40 per gram for raw, high-quality pieces in 2026.

Troubleshooting Common Moldavite Scams

Identifying a scam requires a keen eye for both the stone and the seller's behavior. Many fake pieces are mass-produced in molds, leading to identical shapes across different shops. If you see five stones that look exactly the same, they are definitely factory-made glass. Natural moldavite is always unique in its shape and texture.

• The seller claims the stone is "newly discovered" in a country other than the Czech Republic.
• The stone feels unusually heavy or very warm to the touch compared to other minerals.
• A certificate is provided, but it lacks a stamp from a recognized gemological lab.
• The shop owner becomes aggressive or defensive when you use a magnifying glass.
• The stone has sharp, jagged edges that look like broken bottle glass rather than natural erosion.
• Large pieces (over 20 grams) are offered for less than 2,000 CZK.

Decision Guide: If the stone has elongated bubbles and a matte finish, it is likely real. If the stone is perfectly clear and very shiny, it is likely fake. When in doubt, compare the piece to the displays at the is the Moldavite Museum worth visiting guide to see what quality looks like.
