Like the name says, the Luna three stone diamond engagement ring is inspired by the moon. Set in 18ct white gold, the diamond centre is flanked by two bezel set half moon diamonds. Did you know that half moons are just an oval diamond split into two? This split shank design has two ribbons of bead-set diamonds which gracefully frames the sides of the half moons. Supremely elegant, the Luna is the perfect choice for those wanting a modern take on the trilogy style.

Initially the customer care team got back to me promptly and arranged a virtual meeting with my designer. She was very personable and understood what I wanted, I was after quite a unique design and she guided me through the process and helped a great deal. I was very happy with the whole experience. Our ring arrived and was perfect! Great work Guys!
