  • Since 1983

    Formerly known as STONEX CORP in 1983, our store quickly became a landmark in the 47th Street Diamond District. As the only ground-level store of its kind, STONEX CORP set the standard for quality, service, and trust in gemstones, beads, and pearls, serving generations of jewelers, designers, and collectors.

  • RJP Legacy

    In 2023, the store was acquired by a team of Asian American partners and rebranded as RJP Gems. Today, we continue the STONEX legacy, providing exceptional wholesale and retail service, professional craftsmanship, and a carefully curated selection of pearls, gemstones, and beads for every jewelry professional and enthusiast.

    At RJP Gems, we are dedicated to precision, durability, and beauty. From restringing valuable pieces to preparing new designs, every strand, bead, and gemstone is handled with meticulous attention to detail, ensuring that our customers receive products that meet the highest professional standards.
