## Science over Guesswork When evaluating gold, accuracy is worth thousands of rupees. The traditional 'touchstone' approach involves rubbing your jewelry on a hard abrasive stone and applying nitric acid. Not only does this physically remove traces of your gold, but it also relies heavily on human estimation. ### Enter XRF Technology X-Ray Fluorescence (XRF) is a non-destructive analytical technique perfectly suited for precious metals. - **100% Non-Destructive:** No scraping, no acid, no melting. - **Instant Results:** The machine scans the item and produces a breakdown (e.g. 91.6% Gold, 5.0% Copper, 3.4% Silver) in seconds. - **Deep Penetration:** XRF devices can detect deep plating and core structures, ensuring you aren't scammed and we aren't buying plated fakes. Always choose a buyer who uses XRF. At Neehan Gold Buyers, we let you watch the screen as the machine tests your valuables, allowing complete transparency.
