Core Viewpoint - The article highlights the potential health risks associated with popular "energy stones" and "health stones," emphasizing the dangers of certain jewelry items that may contain toxic substances or pose health hazards [2][3]. Group 1: Health Risks of Popular Items - A customs inspection at Dalian Zhoushuizi Airport revealed a bag of "health stones" with a radiation level of 105 microsieverts per hour, exceeding the background value by 1050 times, equivalent to the radiation from one chest X-ray [3][4]. - A traveler experienced frequent nosebleeds while wearing an "energy stone" for three months, raising concerns about the health implications of such items [5][6]. Group 2: Specific Jewelry Items to Avoid - **1) Xiangsi Bean**: Often mistaken for the red bean in poetry, Xiangsi beans (also known as chicken mother beads) can be toxic if their outer shell is compromised, potentially leading to severe poisoning symptoms [8][12]. - **2) Walnut Bracelets**: While popular among various age groups, walnuts can easily mold, producing aflatoxins, and some vendors may use harmful chemicals to clean them, posing skin irritation risks [13][16][17]. - **3) Dyed Agate**: Many low-cost, brightly colored agate pieces are actually dyed with toxic chemicals like potassium nitrate and silver nitrate, which can accumulate heavy metals in the body and may lead to cancer or genetic mutations [20][22][25]. - **4) Imitation Jewelry**: Made from inexpensive alloys, imitation jewelry may contain harmful metals like lead and nickel, which can cause skin reactions and long-term health issues if absorbed through the skin [26][29][31].
