Each Sideræ jewel is thoughtfully handcrafted in our studio near Milan, where molten gold is cast to capture the fluid beauty of a moment not to be repeated. While skill and precision are deeply involved, every piece appears effortless and spontaneous. Our alternative creative approach uplifts the beauty of diversity and the unexpected: shapes are organic, details unpredictable and no two jewels are ever alike, set apart by their own unique character. Their uniqueness carries the beauty of imperfection—imperfect, yet whole. Learn more about our craft.
