How to Spot Fake Gemstones: A Buyer's Guide

Learn the difference between lab-grown, heated, dyed, and completely natural stones so you can shop with confidence.

The gemstone market is filled with imitations and treatments that can fool even experienced buyers. Knowing what to look for protects your investment and ensures you receive genuine healing energy.

### Common Fakes Glass, plastic, and synthetic lab-grown stones are the most common substitutes. Dyed quartz is often sold as rare stones like tanzanite or blue topaz. Heat-treated stones have altered colors that fade over time.

### Tests You Can Do The temperature test: real gemstones stay cool to the touch. The scratch test: genuine gems are harder than glass. Check for bubbles inside — glass imitations often have tiny air bubbles. UV light can reveal treatments in emeralds and rubies.

### Buy from Trusted Sources Always ask for lab certificates (GIA, IGI, or similar). At Ashoka Exports, every certified piece comes with documentation verifying authenticity. When in doubt, trust sellers with decades of heritage and transparent sourcing.
