Buying gold in Karachi requires verifying its purity before completing a purchase or sale. Hallmarked gold guarantees exact karat weight—whether 24K, 22K, 21K, or 18K—so you pay only for genuine precious metal rather than alloy fillers.
This guide covers how to read gold hallmark stamps, where to get electronic purity tests in Karachi, and how to protect yourself against counterfeit jewelry.
Key Takeaways
- Look for Standard Hallmark Marks: Authentic hallmarked gold carries three distinct stamps: the maker’s logo (e.g., ARY, Hanif), the karat purity mark (916 for 22K, 750 for 18K), and the official assay center symbol.
- Best Testing Method: Request a digital XRF (X-Ray Fluorescence) analyzer test at Sarafa Bazar or major brand testing labs for non-destructive, instant purity verification.
- Keep Official Invoices: Always secure a detailed receipt listing the gross weight, net gold weight, karat purity, and hallmark registration code for reselling or insurance purposes.

3 Reliable Ways to Verify Hallmark Gold in Karachi
- Inspect Stamps with a Magnifying Loupe: Use a 10x jeweler’s loupe to locate the laser-engraved hallmark on the inner band of rings, the clasp of necklaces, or the back of earrings.
- Visit an XRF Testing Center at Sarafa Bazar: Head to major bullion hubs like Liaquatabad Sarafa Bazar, Saddar, or Boulton Market. Independent assayers use XRF machines to measure exact elemental composition without scratching or damaging the metal.
- Verify via Brand Buyback Standards: Reputable Karachi jewelers offer digital laser verification on site and issue stamped certificates matching the piece’s registration number.
