Old Gold Exchange Guide: How Purity Testing Works & How to Avoid Hidden Deductions

Historically, jewellers rubbed ornaments against a black touchstone (कसोटी) and applied nitric acid, which only tested the surface and relied on rough human guesswork. At Mhaswadkar Saraf, we assess the purity of metals using scientific XRF Karatmeters. The customer sees the exact elemental analysis (Gold, Silver, Copper, Zinc) on-screen in real time, guaranteeing absolute mathematical precision and zero guesswork.

A common fear among consumers is what happens when old gold is taken behind closed doors. At Mhaswadkar Saraf, we eliminate this anxiety entirely: from melting to assaying and XRF testing, everything happens right in front of the customer so that the entire process is completely transparent. • Step 1 — Visible Weighing: Your gold is weighed on a certified 0.001g digital balance with a dedicated display facing you. • Step 2 — Detaching Non-Gold Parts: Stones, pearls, threads, and wax are detached in your presence, and all detached stones are returned to you. • Step 3 — Open Melting: If melting is required to form a uniform sample bar, melting takes place directly in front of you. The metal never leaves your line of sight. • Step 4 — Instant XRF Assaying: The cooled sample is placed in the XRF chamber right before your eyes, and the purity percentage is printed immediately on a digital test report.

At Mhaswadkar Saraf showrooms in Satara and Koregaon, our exchange valuation follows strict, open digital procedures. Because we assess purity using precision XRF machines in front of you, you receive the full, honest market value of your precious metal based on today's published benchmark rates with zero arbitrary deductions.
