This high jewellery Serpenti necklace from famed Italian jeweller Bulgari sums up the house style perfectly. Bulgari is famous for its use of colour, and this red-carpet-worthy necklace comprises 94 round Zambian emerald beads totalling an incredible 1,021 carats. Look closer and you will spot the iconic Serpenti snakes, which unite the double and single strands of emerald beads. But these sparkling pink gold serpents are not merely decoration. Set with 24 buff-top rubies, four pear-shaped brilliant cut diamonds and pavé diamonds, the necklace is transformable and these colourful snakes can be removed and worn as earrings, which makes this one-of-a-kind jewel an investment piece that will be worn time and time again.
