The details
A round synthetic onyx stone, deep and uniformly black, sits at the center of a polished solid sterling silver band. The contrast is immediate and intentional: cool bright silver against matte black, a pairing that reads modern without trying too hard. The band is wide enough to register as a real presence on the finger while staying comfortable through a full day.
Solid sterling silver means the ring can be polished back to its original shine whenever it needs it, and the clean, ungendered silhouette means it belongs on any hand. Dress it up for an evening or wear it every day alongside other bands. Either way, the black and silver combination holds its own.

Jewelry care
- Sterling silver darkens naturally with air. A silver polishing cloth brings the shine back, and an airtight pouch keeps it there.
- Put jewelry on last, after lotion and perfume, and take it off before showering, swimming or sleeping.
- Store each piece on its own in a soft pouch so it doesn't scratch.
