17克旧金“换新”仅得9克金项链？涉事金店：并非克重1:1，而是价值1:1

Group 1 - Gold prices have rebounded, with spot gold reaching $5,100 per ounce for the first time since January 30, and later adjusting to $5,071.605 per ounce, still at historical highs [1][2] - The concept of "gold preservation" has led to an increase in "gold exchange" consumption, where consumers trade in old gold jewelry for new pieces, paying only a processing fee [3] - A consumer, referred to as Aunt Yan, experienced issues during her gold exchange, where she was promised a 1:1 exchange but received significantly less weight in return [5][7] Group 2 - The store clarified that the "1:1 exchange" referred to value rather than weight, with the new item priced at 21,567 yuan, resulting in a price of 2,341.69 yuan per gram for the new necklace, which exceeds market prices [9][11] - Another consumer, Ms. Qian, reported a similar experience where her old gold jewelry was exchanged for significantly less weight, with a price per gram exceeding 2,000 yuan, also above market rates [11] - Legal experts suggest that while the store provided products for exchange, the misunderstanding regarding the valuation method may not constitute fraud, but consumers can argue for contract rescission due to significant misunderstanding [12]
