Core Viewpoint - The article highlights the health risks associated with low-quality jewelry that is falsely marketed as gold or silver-plated, revealing that many such products do not meet the required standards and may contain harmful heavy metals [3][4][5]. Group 1: Product Quality Issues - Many jewelry items marketed as gold or silver-plated do not meet the required thickness standards for precious metal coatings, with 17 out of 21 samples tested failing to meet these standards [4]. - Specific examples include a "silver-plated" bracelet with a silver coating of only 0.24 micrometers, far below the required 2 micrometers, and a "gold-plated" bracelet with a gold coating of only 0.03 micrometers, well below the required 0.5 micrometers [4]. Group 2: Health Risks - Some jewelry items contain hazardous heavy metals, such as cadmium, which can pose significant health risks. One tested pair of earrings labeled as S925 silver was found to have cadmium levels exceeding the standard by over 9000 times [5][6]. - Cadmium is recognized as a highly toxic heavy metal and classified as a Group 1 carcinogen by the International Agency for Research on Cancer [5]. Group 3: Market Regulation and Consumer Awareness - The prevalence of low-quality jewelry in wholesale markets and on e-commerce platforms underscores the urgent need for stricter regulation and oversight of the jewelry market [8]. - Regulatory authorities are urged to enhance supervision and impose penalties on businesses that engage in false advertising and substandard product offerings [8]. - Consumers are advised to exercise caution and prioritize quality and safety over low prices when selecting jewelry [9].

Core Viewpoint - The article highlights the health risks associated with low-quality alloy jewelry, particularly the prevalence of "jewelry dermatitis" caused by allergic reactions to heavy metals like nickel and cadmium, and the misleading marketing practices surrounding these products [1][2]. Group 1: Health Risks - Many patients have developed skin conditions due to prolonged wear of alloy jewelry, leading to symptoms such as redness, itching, and peeling [1]. - A significant number of tested jewelry samples (17 out of 21) failed to meet the required thickness standards for gold and silver plating, with some items having plating thicknesses as low as 0.03 micrometers for gold, far below the standard of 0.5 micrometers [2]. - Certain jewelry items contain dangerously high levels of cadmium, a known carcinogen, with one sample exceeding the safe limit by over 9000 times, posing serious health threats to consumers [2]. Group 2: Market Practices - The jewelry market is rife with issues of false advertising and substandard products, where many items are sold at low prices without proper quality assurance [1][3]. - Retailers often mislabel their products, claiming they are made of precious metals while using cheaper alloys, misleading consumers about the safety and quality of the items [2]. - The prevalence of these low-quality products is not limited to physical markets but is also widespread on e-commerce platforms and live-streaming sales [3]. Group 3: Regulatory Recommendations - There is an urgent need for stricter regulations and oversight in the jewelry market to combat false advertising and ensure product safety [4]. - Regulatory bodies should increase inspections and penalties for non-compliant products to protect consumer rights and public health [4]. - E-commerce platforms must take responsibility for screening and verifying the quality of jewelry sold on their sites to prevent the circulation of hazardous items [4].
