Introduction
Wishful thinking in gem identification is one of the most dangerous traps in gemology. When you want a stone to be valuable, confirmation bias can blind you to evidence that proves otherwise. This guide explains how to avoid the costly mistakes that come from desire overriding discipline.
Is Wishful Thinking the Most Dangerous Trap in Gem Identification?
What You’ll Learn
- What wishful thinking means in gem identification
- How confirmation bias in gemology leads to mistakes
- Real-world examples of gem identification errors
- Practical steps to avoid bias when buying or testing gems
The Psychology Behind the Trap
Wishful thinking in gem identification happens when someone wants a stone to be valuable and ignores contradictory facts. In psychology, this is called confirmation bias. A green stone may be accepted as emerald, even if inclusions suggest it is glass.
Costly Real-World Examples
- A ruby worth $250,000 at auction turned out to be synthetic. The buyer admitted his wishful thinking stopped him from requesting lab verification.
- In Bangkok, a dealer spent $40,000 on “emeralds” that testing later proved were dyed quartz.
These cases show why gem buyers must resist bias.
How to Avoid Wishful Thinking in Gem Identification
- Use multiple tests (refractometer, spectroscopy, fluorescence).
- Always request a gemological lab certificate before major purchases.
- Ask yourself: “Am I ignoring evidence because of wishful thinking?”
