Square Round Signet Ring in Sterling Silver or Gold Vermeil

Discover timeless style reimagined in the Square-Round Signet Ring – a modern classic designed for those who appreciate clean lines and thoughtful craftsmanship. With its sleek, polished surface and distinctive geometric shape, this ring strikes the perfect balance between boldness and refinement. The square-round design – a fusion of crisp angles and smooth curves – offers a subtle yet striking silhouette that elevates any look.

Handcrafted in London’s historic Hatton Garden, each piece is made using the ancient lost-wax casting method, a technique that ensures every ring carries a unique finish and character. This traditional process, paired with contemporary design, creates a piece that feels both rooted in heritage and unmistakably modern.

Crafted from recycled .925 sterling silver or luxuriously layered 18ct gold vermeil, the Square-Round Signet Ring is as sustainable as it is stylish. The face of the ring measures 18 mm wide by 17 mm high, with a bevel height of 5 mm that gives it a strong, sculptural profile. The band itself has a solid 2 mm thickness, offering a comfortable and substantial feel on the hand.

Perfect worn solo or as part of a curated ring stack, this signet is designed to make a quiet yet confident statement – a future heirloom with a bold architectural edge.

MOCA Jewellery is a North London–born, handcrafted jewellery brand rooted in storytelling, memory, and bold self-expression. Each piece reflects the beauty of imperfection — tactile, raw, and unapologetically distinct.

The name MOCA is a tribute to family, drawn from the initials of the founder’s parents and brother. What began as a childhood love of craft evolved into a lifelong creative journey, shaped by formal silversmithing training in Toronto. The result is a brand that blends traditional techniques with a modern, expressive aesthetic.

Known for sculptural silhouettes and organic textures, MOCA Jewellery plays with asymmetry and subtle imperfections to create truly unique pieces. Each design favours authenticity over polish — quiet statements of individuality made to be worn, lived in, and remembered.

Sustainability and ethics are central to the brand’s philosophy. Recycled silver and responsibly sourced stones are used wherever possible, with each piece handmade in small batches or to order — keeping waste low and attention high.

Whether you’re marking a milestone or adding character to the everyday, MOCA Jewellery invites you to wear your story. With a style that’s elegant yet eccentric — a little bold, a little gaudy — MOCA Jewellery celebrates joy, nostalgia, and the freedom of self-adornment without apology.

From its London roots to a growing global following, MOCA Jewellery remains true to its values: craftsmanship, character, and the beauty of making something that lasts.
