Genuine vs Fake Gemstone Bracelets — How to Verify

Genuine vs Fake Gemstone Bracelets

How to verify what you're buying

Gemstone jewelry is one of the easiest product categories to fake — glass, dyed quartz, and heat-treated stones are common substitutes sold as natural. Here's how to tell the difference before and after you buy.

Before you buy

  • Ask for the lab certificate upfront — not after you've already paid
  • Be cautious of prices that seem far below market rate for the stone type — natural AAA-grade stones have a real cost floor
  • Check whether the seller specifies the stone's grade (AAA, AA, etc.) or just calls it "natural" with no detail

After you receive it

  • Look for inclusions. Natural stones have minor internal imperfections. Perfectly clear, flawless beads are usually glass or synthetic.
  • Check the weight. Natural stones typically feel heavier than glass of the same size.
  • Touch test. Natural stones feel cool initially and warm slowly; glass and plastic warm up almost instantly.
  • Match the certificate. The lab certificate should describe the specific stone, its origin, and treatment status — cross-check it against what you received.

These checks are indicative, not proof. The only reliable proof of a natural stone is an independent lab report — here is how to read and verify yours.
