Best of Boston 2017!!! Best Fine Jewelry!

We are thrilled to announce that we have won Boston Magazine’s Best of Boston ® 2017 Best Jewelry, Fine in Boston! It is such an incredible honor to be receiving this highly esteemed recognition for two consecutive years.

It all started with the great vision that Quadrum’s owner, Cynthia Kagan, had 39 years ago; to open a gallery that would give space for contemporary jewelry artists to showcase their work. She worked tirelessly to make Quadrum what it is today, and we are now blessed with an amazing staff who continue the tradition of putting their all into curating and representing the finest artist jewelry collection around. Director Sia Maravelias, Assistant Director Amy Renneisen, and the Quadrum staff are intensely focused on this field of artistic expression, as shown in their passion, energy, and devotion. It is by providing an extensive level of customer service that your experience will be unsurpassed and met with the ultimate satisfaction that comes with giving or wearing a beautiful piece of jewelry.
