别买、别戴！重金属严重超标

Core Viewpoint - The rise of "sand gold" jewelry, which mimics the appearance of gold but is sold at a much lower price, has gained popularity among consumers due to the high prices of gold this year. However, the actual composition and quality of these products are questionable, with many not containing any gold at all [1][12]. Group 1: Market Dynamics - "Sand gold" jewelry is marketed as a low-cost alternative to gold, with prices ranging from a few hundred yuan to over a hundred yuan in live-streaming sales [1][11]. - Many sellers claim that "sand gold" products are made from materials that do not fade and are resistant to burning, creating a perception of high quality [1][3]. - The term "sand gold" is often used misleadingly, with some sellers using names similar to well-known brands to attract customers [3][4]. Group 2: Composition and Quality - "Sand gold" is defined as mineral rock containing about 5% gold, but most products sold under this name do not contain any gold and are primarily made from copper-nickel alloys or thinly gold-plated materials [12][14]. - The gold plating on these products is often less than 0.05 microns thick, which does not meet national standards for gold-plated items, leading to rapid wear and potential exposure to harmful metals like nickel [16][18]. - Testing has shown that some "sand gold" jewelry can release nickel at levels exceeding national safety standards, posing health risks to consumers [18][20]. Group 3: Legal and Regulatory Concerns - There are legal implications for sellers who engage in false advertising, as they may face penalties under Chinese law for misrepresenting their products [22]. - The industry is under scrutiny for the widespread misleading claims regarding the quality and composition of "sand gold" jewelry, prompting calls for better regulation and consumer protection [22].
