Mastoloni Pearls

Across from Bryant Park sits the discreet eighth floor that houses Mastoloni Pearls, a jewel-box workspace where design and craftsmanship meet. In the heart of Midtown’s jewelry district, the studio turns raw nacre into polished necklaces, earrings, and cufflinks for collectors who prize singular pieces. Clients who want a single strand or a custom suite drop by with sketches or requests, trusting the hands guiding the loupes.

Custom designs begin with a client-side consultation, then move to bead sourcing, stringing, and final clasp engineering. Off-the-peg strands are refined at the same benches, ensuring every finish meets atelier standards. Whether an heirloom-quality rope or a daytime choker, each unit ships with a gemological certificate stapled to its box.
