Our Family Legacy

Anto Aboyan—co-owner, artist, and passionate craftsman— is the heart and soul of the creative team at Adamas Fine Jewelry. Starting as a bench jeweler at the age of 18, working alongside and mentored by his uncle, Anto began his lifelong love for the art of jewelry making.

It wasn’t long before Anto opened his first shop in Boston’s famed Jeweler’s Building. With a passion for unique and handcrafted custom design, he soon branched out in a more intimate and artistic direction, and in 1997, Anto and his sister Veronica joined forces to establish Adamas Fine Jewelry. 

Having also honed her skills through summers working for family members in the jewelry business, Veronica plays a vital role in jewelry design, managing day-to-day operations, ensuring a seamless customer experience, and fostering overall growth.
