Many local jewelers also act as diamond buyers , purchasing stones directly from individuals. This includes buying back jewelry for its metal weight or reselling pre-owned, antique, or estate pieces.
Jewelers typically source their diamonds through a multi-tiered supply chain that ranges from direct mining partnerships to secondary market purchases from the public . The primary ways jewelers acquire diamonds include:
Jewelers use specialized online marketplaces (like Alibaba or Etsy ) and B2B platforms to find unique inventory. For extremely rare or "elite" gems, jewelers and collectors may turn to high-end auction houses like Christie's and Sotheby's .
Most independent and mid-sized jewelers buy finished, polished stones from diamond wholesalers or distributors. These middlemen purchase large volumes from manufacturers and provide retail stores with a variety of styles, metals, and gemstone qualities.
Large-scale retail operations often bypass wholesalers to work directly with jewelry manufacturers . These manufacturers design and produce high-quality pieces in bulk, often based in global cutting and polishing hubs like Surat , India .
