US Jewelry Manufacturers
The Leading Jewelry Manufacturers and Suppliers
Established in 1983 by a small group of distinguished jewelry manufacturers in the USA, The Plumb Club has become one of the leading go-to supplier organizations for jewelry suppliers. Today, The Plumb Club is a unique coalition of leading, responsible and important suppliers spanning all facets of the jewelry, diamond and watch industries. The Plumb Club’s membership accounts for a significant percentage of the domestic fine jewelry market.
All Plumb Club members adhere to very high standards of conduct on a personal and professional level. Members are also asked to sign the Plumb Club “Code of Responsibility” annually, agreeing to uphold high standards of integrity, ethics, morals, and honesty. This enables retailers and manufacturers to collaborate in an environment of respect and integrity.
Responsible Jewelry Council
In 2019, members of the Plumb Club collectively decided, in the spirit of solidarity, to make it mandatory for all members to become certified members of the Responsible Jewelry Council. The vote was unanimous, uniting us through undivided support of our mission and vision.
Why is it so important that Plumb Club members also become a part of the Responsible Jewelry Council? Because the RJC is the most respected leader in the jewelry and timepiece industry, when it comes to setting standards.
Members help the RJC make the industry – and world – a more responsible and sustainable place, contributing to a brighter future where everyone in the industry can work towards the same goals that unite and bind us.
