This 18kt gold Rhea necklace – depicting a whimsical beetle – is a beguiling expression of Daniela Villegas’s obsession with the natural world. It’s crafted in the USA with a large cabochon 38.2ct azurite and an oval-cut 5.3ct blue tourmaline alongside pavé-set emeralds totalling 2.05ct and sapphires totalling 1.45ct. Frame it with a deep V-neck to showcase the glittering precious elements and watch it become a modern heirloom.
