Carefully inspect the specimen for structural integrity, especially if it’s intended for display or further processing.
5. Mistake 5: Falling for Fakes or Misrepresentations: The market sometimes includes synthetic or imitation minerals presented as natural. Be cautious of unusually low prices for rare items or specimens sold without clear identification. Buying from reputable dealers in Barcelona or international companies with strong reputations is crucial.
6. Mistake 6: Neglecting Proper Storage and Handling: Some minerals are delicate, reactive to light, or sensitive to atmospheric conditions. Improper storage can lead to degradation or damage. Learn about the specific care requirements for the minerals you acquire to preserve their condition and value over time.
7. Mistake 7: Not Considering the End Use: Whether for collection, decoration, or industrial use, ensure the rough rock or mineral meets your specific needs. An aesthetically pleasing but chemically impure mineral might be unsuitable for certain industrial processes, while a highly pure but unattractive industrial grade mineral might not be ideal for display.

By being aware of these common mistakes and adopting a thoughtful, informed approach, buyers can confidently navigate the world of rough rocks and minerals, ensuring their acquisitions are both satisfying and valuable in 2026 and beyond.
