This striking Everlasting Love necklace marks a new chapter for K&Co, as this is the first piece the house has ever produced using aluminium. This alternative metal has been wielded to create chevrons in shades that range from hot pink to dark turquoise, achieved through a specialised method of heat treatment. Interspersed with round brilliant diamonds, these arrows are a reminder of the importance of navigation at sea, where losing direction can be perilous. Follow the trail of this waist-length necklace and it will lead you to a magnificent rubellite. The stone has been custom cut to reference gems from the Mughal era, with a rose-cut pattern and a smooth, flat underside.
