Our Story

History

Marcy Levy’s lifelong love for diamonds began in Israel at age 14, when the young Marco developed in interest in cutting and repairing stones – a distinctive talent within the highly specialized business of fashioning rough stones into stunning, finished diamonds. Having established his overseas reputation, Marco moved to the United States, working alongside expert jewelers in New York City until he relocated to the west coast and established The Diamond Source.

Since opening in Old Town San Diego, The Diamond Source has catered to a global family of customers looking to match life’s biggest moments with one of Marco’s stones or custom designs. His second store, featuring some of Marco’s museum-quality treasures — extraordinary pieces he considers irreplaceable, opened on prestigious Girard Avenue in La Jolla, California in 2007.

Marco is dedicated to educating his customers about the differences in value and brilliant beauty of the ideal cut diamond. His expert eye can spot even the smallest differences in proportions, clarity, and other factors that determine whether a diamond will retain and gain value over the years.

Experience

The difference in The Diamond Source, as Marco believes, is the commitment to putting every stone through a rigorous inspection, one that guarantees the customer is getting the highest quality diamond. Having shared his knowledge and values with his family, Marco now operates The Diamond Source as San Diego’s premier custom jeweler, dedicated to delivering a lifetime of unparalleled service to every person who purchases a diamond in-store and online.

In a world in which you can purchase stones online without every seeing or holding them in person, Marco is dedicated to educating his customers about the differences in value and brilliant beauty of the ideal cut diamond. His expert eye can spot even the smallest differences in proportions, clarity, and other factors that determine whether a diamond will retain and gain value over the years.

“The designs just come to me when I look at the diamonds. I can see the finished jewelry.”
– Marco Levy

Our goal is to leave you feeling like an expert.
