About NovaBlock
A family-owned US jewelry store with 20 years at the bench.
NovaBlock began as a small family counter where repairs, wedding bands, and hand-set diamonds were handled with the same care as heirlooms. Twenty years later, the studio is still family owned, US based, and built around private service rather than volume.
The NovaBlock team specializes in custom made jewelry: engagement rings shaped around a chosen stone, restored family pieces, redesigned heirlooms, diamond necklaces, tennis bracelets, earrings, and everyday pieces made to last. Every project is guided by clear consultation, hand-selected diamonds, artisan bench work, and patient finishing.
