(NEW YORK) – For over 40 years, The Plumb Club has attracted and provided the jewelry retail community with a top-tier roster of the industry’s most important suppliers. That roster of responsible and important companies has continued to expand with two new distinguished members being added in 2026. With these new companies, the Club represents well over 100 jewelry, watch, and service brands. The two new members are:
Guild+Facet: This premier jewelry manufacturer is built on a foundation of over three decades of family heritage and passion, dedicated to bringing a retailer’s unique vision to life. As a trusted manufacturing partner, they deliver custom excellence, ranging from bespoke single pieces to full-scale product lines. Their workshop bridges the gap between state-of-the-art technology and meticulous hand finishing, ensuring every piece is crafted with precision and care. Their retailer focus supports their customers’ growth through expert advice, reliable customer service, and a commitment to guaranteed on-time delivery.
Matthew Ego, CEO and founder, states, “Throughout my 27 years in the industry, The Plumb Club has been the standard of excellence within the industry. Guild + Facet has forged a reputation with the same principles that the Club is known for, and we are excited to grow within that environment and culture.”
Shivani Gems, Inc: Founded in 1984, the company is proud to serve the industry as a leading manufacturer and distributor of natural, fancy-shaped diamonds. Backed by offices in Antwerp and Mumbai, along with a diamond cutting factory in Surat, they have built a reputation as a service-driven house, supplying single stones, matched pairs, and calibrated layouts from 0.02 to 2 carats. Shivani is synonymous with quality and precision in marquise, pear, and oval diamonds as well as across fancy shapes. Today, that legacy has evolved into finished jewelry where the beauty and intricacy of fancy shapes are expressed in an entirely new light.
Mehul Shah, president of Shivani Gems, Inc., says, “We have been exhibiting at JCK since its inception and have seen the show evolve. However, The Plumb Club has always been the hallmark of excellence. For Shivani Gems to be recognized as a new member is a true honor and a testament to our work and integrity as a trusted diamond supplier for over 40 years.”
Roger Forman, president of The Plumb Club, commented, “The Plumb Club’s commitment to providing great value to the industry across several initiatives, including our membership, is highlighted even more with these two new members.”
All Plumb Club Members must meet stringent requirements of business ethics, practices, and conduct, as well as human rights, social and environmental responsibility, and be members of The Responsible Jewelry Council.
