This two-piece Fusion combination is formed by two interlocking end-rings. One crafted in 18kt white gold adorned with meticulously set brilliant-cut diamonds along the edges, and the other in 18kt white gold featuring black Hyceram, a high-quality compound mastered only by the most skilled jewellers. First envisioned by Nina Koppel in the 1990s and introduced in 2000, the Fusion ring has established itself as a timeless Georg Jensen jewellery icon that allows for endless customisation and endless expression.
