ADCO Diamond
About
ADCO Diamond is a family-owned, sister-led jewelry studio in Downtown Boston specializing in GIA-certified, conflict-free diamonds for engagement rings, wedding bands and other jewelry. Its collection ranges from diamond rings and eternity bands to sapphire and ruby pieces, bracelets, earrings and pearl necklaces. The showroom reflects an artistic side, with modern showcases and colorful custom artwork on the walls, and custom design is a central part of the business.
The family entered the diamond trade more than 40 years ago, sourcing stones and building global relationships. Daughters Aline and Rina, who arrived with their parents in 1975, studied biology and graphic design at Boston University and then enrolled at the Gemological Institute of America before joining the family business. With them on board, ADCO grew from a wholesale operation into a retail jeweler, combining gemological knowledge with design.
