Mark and Candy Udell are the dynamic husband-and-wife duo at the helm of London Jewelers, one of America’s most iconic and enduring family-owned luxury jewelry retailers. Together, they have transformed a single-store operation, founded in 1926, into a multi-store luxury powerhouse known for innovation, craftsmanship, and unparalleled customer service.
Mark Udell, Chief Executive Officer, officially joined the family business in 1973 after graduating from the University of Miami and gaining early retail experience at Mayor’s Jewelers in Florida. A third-generation jeweler and grandson of founder Charles London, Mark brought a lifelong passion for watches and fine jewelry to the business. Under his leadership, London Jewelers expanded from its original Glen Cove location into a prestigious network of boutiques across Long Island and New Jersey. His industry expertise and deep relationships with top-tier brands—including Rolex, Patek Philippe, Cartier, Bulgari, Van Cleef & Arpels, and David Yurman—have positioned London Jewelers as a benchmark in U.S. luxury retail, with 18 stores.
That same year, Mark married his college sweetheart, Candy Udell, who joined him in the family business and now serves as President of London Jewelers. A graduate of Hofstra University with a degree in communications, Candy brought creative flair and strategic vision to the company. She has played an essential role in merchandising, branding, advertising, and store design—helping to shape the company’s identity and elevate its customer experience. Her leadership has also been pivotal in launching meaningful philanthropic initiatives, including the founding of the Rescue Paw Foundation, which funds no-kill animal shelters and spay/neuter programs. Candy also designed the Paw Jewelry Collection, with proceeds supporting animal welfare efforts.
The Udells' shared leadership has driven major milestones for London Jewelers, including the 2025 opening of the world’s first Rolex Boutique in East Hampton, the continued expansion of their flagship store in Manhasset, and the opening of their fifth store in The Mall at Short Hills in New Jersey.
Together, Candy and Mark have received numerous honors for their contributions to the jewelry industry and beyond. In 2024, they were jointly awarded the WatchPro USA Lifetime Achievement Award. Mark has been inducted into the National Jeweler Retailer Hall of Fame, named Jeweler of the Year by the New York State Jewelers Association, and honored with the Diamonds Do Good Community Impact Award. Candy’s accolades include the WJA Award for Excellence in Retail, the AGS Triple Zero Award, and her own induction into the Retailer Hall of Fame in 2023, among many others.
Beyond business, the Udells are dedicated philanthropists, supporting more than 100 local charities annually through London Jewelers. Their efforts span healthcare, education, the arts, animal welfare, and community safety.
Today, Candy and Mark are proudly mentoring the fourth generation—their daughter Randi, son Scott, and nephew Zachary—to carry forward the values that have defined London Jewelers for nearly a century: integrity, innovation, excellence, and treating every customer like family.
