Neptune
Round solitaire engagement ring with milgrain and pavé diamond halo and pavé band
Named after the god of the sea, our Neptune ring bursts with expression and artistry. This solitaire engagement ring has a large halo decorated with milgrain and bead bright diamond pavé, echoing the spray of an ocean wave crashing against the shore. The shape of the ring’s face is made of scalloped platinum, creating a unique floral-inspired engagement ring with a round brilliant centre diamond held in eagle claws. The Neptune also has an ethereal ½ eternity diamond pavé band with sloping cathedral shoulders that connect to the ring’s lattice-work basket. If an ornate diamond engagement ring is what you’re after, then look no further than the Neptune ring in platinum, which pairs perfectly with rings from our curved wedding band collection.
