A century of combined experience, one company

With over 100 years of combined experience in estate and antique jewelry, it just made sense for four friends and longtime associates to form their own company. Richard Mampe Sr., Max Weiner, Jeffrey Zayas, and Joseph Cileone founded Beneficial Estate Buyers in 2007 as a full-service estate jewelry company, specializing in estate jewelry buying events and trunk shows.

Based in the heart of Philadelphia's storied Jewelers' Row — the country's oldest diamond district — Beneficial works with retailers across the country to produce unique events that are beneficial to both retailers and their customers.
