Sulphate Ring
plain, no diamonds
The Sulphate Ring is a softened counterpart to the original, defined by its rounded edges and fuller proportions. A quiet shift from strict geometry, its curved silhouette adds weight and volume while preserving a sense of clarity. Designed with a grounded presence, it offers a subtle alternative for those drawn to form with a gentler touch.

Please take note that naturally derived diamonds and gemstones vary in weight, even if they are of the same type and size.
The Sulphate Collection
The Sulphate Collection is the second contemporary collection. The overall silhouette remains familiar but becomes more rounded and calm. Diamond accents are placed intentionally to create a sense of discipline and harmony. Although the pieces look fuller, some are carefully hollowed to keep them light and comfortable to wear. This collection is inspired by my admiration for Japanese culture — their approach to design, discipline, and understated taste.
Sulphate is an artist. He carries his favourite pencil everywhere, always sketching and imagining what could be different. He wasn’t great at first, but through practice, he found his very own style. Guided by curiosity, Sulphate is drawn to contemporary and minimal forms, constantly exploring new ways to create and express through design.
