Group 3: Industry Challenges - The crystal market is plagued by counterfeit products and misleading marketing practices, with many sellers using techniques like dyeing and acid washing to create fake crystals, leading to inflated prices and consumer deception [5][18]. - The lack of industry standards and regulatory oversight makes it difficult for consumers to protect their rights, as evidenced by over 5,000 complaints related to crystal purchases on consumer complaint platforms [18][29]. - The market is becoming increasingly competitive, with over 42,600 crystal-related enterprises in China, leading to a saturated market where genuine businesses struggle to thrive [31][33].
