A yellow gold solitaire engagement ring is a classic and timeless choice for those seeking a traditional and elegant design. It features a single diamond as the centrepiece, set in a yellow gold band. The term solitaire refers to the single diamond, which is the focal point of the ring. Yellow gold has been a popular metal choice for engagement rings for centuries due to its warm and rich colour. It adds a touch of warmth and traditional charm to the ring, creating a beautiful contrast with the sparkling diamond.
