别上当！“沙金” 不是黄金，购买需谨慎

Core Viewpoint - The rise in gold prices has led to the emergence of "sand gold" jewelry as a cheaper alternative, but it is important for consumers to understand that sand gold is not real gold and is often of inferior quality [1][5]. Industry Analysis - The market for sand gold jewelry is characterized by a low entry barrier, allowing small workshops and merchants to operate without adequate regulation, resulting in a proliferation of substandard products [7]. - There are currently no national standards for sand gold products, which enables unscrupulous merchants to exploit the situation [7]. - Consumer knowledge about precious metals is limited, making them susceptible to misleading marketing and low prices, which complicates their ability to discern product quality [7]. Product Quality Concerns - Some sand gold jewelry has been found to have nickel release levels exceeding safety standards by over a thousand times, posing potential health risks such as skin allergies and inflammation [3]. - Merchants have been known to forge testing certificates and engage in false advertising, misrepresenting ordinary alloys as "Vietnam sand gold" or "Myanmar sand gold," misleading consumers into believing they are purchasing gold [5]. - Consumers often find that the actual products do not match the high-quality representations seen in live broadcasts, with many items being dull in color, prone to fading, and made from rough materials [5]. Consumer Awareness and Protection - The Fujian Consumer Protection Committee has issued warnings that sand gold is essentially a copper-nickel alloy, and consumers should be cautious and enhance their understanding of the differences between sand gold and real gold [7][8]. - Consumers are advised to be vigilant against exaggerated claims and low prices that deviate significantly from market norms, as these are often indicators of inferior products [8]. - Simple methods for consumers to distinguish real gold from fake include checking color, weight, and sound, as pure gold has a distinct rich yellow color, a heavy feel, and produces a dull sound when dropped [8][9][10].
