BUYER'S GUIDE

Original vs Fake Gemstone

Q: How can I tell if a gemstone is real or fake?

The only reliable way is laboratory certification from reputed labs (GIA, IGI, GJEPC). Home tests include: checking for natural inclusions (real gems aren't perfect), weight test (real gems are heavier than glass), and temperature test (real gems feel cold). However, sophisticated fakes can pass home tests - always get certification.

Q: Which lab certification is best for gemstones in India?

For gemstones in India, trusted certifications include: GIA (Gemological Institute of America) - global gold standard, IGI (International Gemological Institute), GJEPC (Gem & Jewellery Export Promotion Council), and Gemmological Institute of India (GII). Always verify certificate authenticity online.

The extra cost of certification (Rs 500-2000) is negligible compared to the price of the gem and ensures you get authentic stones.
