Perform an Acid Test with Professional Assistance ✔ The acid test is one of the oldest and most trusted methods for determining gold purity. A small sample of the jewellery is rubbed onto a testing stone, and specialized testing acids are applied to observe the chemical reaction. Different acid concentrations correspond to different karat levels, helping identify whether the jewellery is genuine 14K, 18K, 22K, or 24K gold. Since improper handling may damage the jewellery or produce inaccurate results, this test should always be conducted by an experienced jeweller or certified gold testing laboratory. ◆ Professional acid testing provides reliable purity verification. ★ Never attempt this test on valuable jewellery without proper training. ➜ Combining acid testing with hallmark certification and XRF analysis offers the highest confidence in gold authenticity. #AcidTest #GoldPurity #GoldTesting #AuthenticGold #JewelleryGuide #GoldBuying #CertifiedGold #GoldInspection #GoldInvestment #GoldRate
