Meet Our Founder

Alan Lemmerman, the owner and founder of Nathan Alan Jewelers, is celebrating over 40 years as the only independent jeweler in South Coast Plaza. Alan's journey at South Coast Plaza began in 1980 with the opening of Chain Reaction, a jewelry store specializing in high quality Italian 14 karat and 18 karat gold chains, earrings, pendants, charms and rings. It was the first store of its kind in the country. Four years later, the name was changed to Nathan Alan Jewelers and the specialty became diamond and gemstone fine jewelry, particularly diamond engagement rings and wedding bands. 

His commitment continues to be offering exceptional design, impeccable quality, excellent value and outstanding customer service. Nathan Alan Jewelers has a vision of creating a unique and beautiful experience for their clients while maintaining their dedication to continued growth and improvement.
