What is the quality mark on jewelry?
Could you please elaborate on the concept of a quality mark on jewelry? I'm curious to understand how it differs from other forms of labeling or branding, and what specific criteria it represents. Is it a guarantee of authenticity, craftsmanship, or both? Furthermore, how does one recognize a legitimate quality mark and ensure that their jewelry is truly certified as high-quality? Finally, are there any notable organizations or institutions that are renowned for issuing these quality marks, and how do they ensure their credibility and integrity in the industry?
