Core Viewpoint - The article emphasizes the importance of identifying genuine gold amidst rising gold prices and the prevalence of counterfeit products in the market. It provides several methods for consumers to distinguish real gold from fake alternatives. Group 1: Identification Methods - Method 1: Look for the hallmark. All gold jewelry must have a hallmark indicating its material and purity. Different purities have distinct hallmarks, such as Au999 for 99.9% gold, Au750 for 75% gold, and Au585 for 58.5% gold. Markings like 18KRGP indicate gold-plated items with low gold content [3][6]. - Method 2: Use a magnet. Gold is non-magnetic, so using a magnet can help identify counterfeit items that may contain magnetic metals like iron or nickel. If the item is attracted to the magnet, it is likely fake [5][6]. - Method 3: Scratch test with a needle. Gold is soft and can be scratched easily, leaving a gold-colored mark. If a needle glides smoothly and leaves a gold mark, it is genuine; if not, it may be a fake [8][13]. - Method 4: Density test. Gold has a high density of approximately 19.3 g/cm³. By measuring the weight and volume of the gold item, one can calculate its density. A significantly lower density suggests it may be counterfeit [10][11]. - Method 5: Ceramic scratch test. Using an unglazed ceramic surface, scratching the gold should leave a gold mark. If the mark is black or gray, the item is likely not genuine [13].
