别买、别戴！这种“大金镯子” 重金属严重超标

Core Viewpoint - The rise of "sand gold" jewelry, which mimics the appearance of gold but is made from low-cost materials, has gained popularity as a cheaper alternative due to the increasing gold prices. However, most of these products do not contain actual gold and are often misleadingly marketed [1][2][3]. Group 1: Product Characteristics - "Sand gold" jewelry is claimed to be made from materials that do not fade and are resistant to fire, with prices ranging from a few hundred yuan [1]. - The term "sand gold" refers to minerals containing about 5% gold, but many sellers do not clarify the actual material composition [1][2]. - Most "sand gold" products are made from brass with a thin layer of gold plating (0.05 microns), which can wear off over time [2][3]. Group 2: Market Dynamics - Sales of "sand gold" jewelry are booming, with some sellers reporting monthly sales exceeding 100,000 pieces [2]. - The price transformation from factory cost (around 10 yuan) to retail (approximately 40 yuan at night markets) highlights significant markup, with online sales reaching over 100 yuan [3]. Group 3: Health and Safety Concerns - Many "sand gold" products contain no gold and are primarily copper-nickel alloys, raising concerns about potential allergic reactions due to nickel release [4][5]. - The nickel release from some products can exceed national safety standards by over a thousand times, posing health risks to consumers [5][6]. Group 4: Legal Implications - There are ongoing consumer complaints regarding allergic reactions from wearing "sand gold" jewelry, leading to potential legal actions against sellers for false advertising [7]. - Legal experts indicate that selling counterfeit products can result in severe penalties, including fines and imprisonment, under Chinese law [7].
