Jewellery designer Kat Florence wears a pair of Brazilian Paraiba tourmaline studs every day, and you can too. These simple studs bring the neon colour of the Paraibas to life within an icy setting of 18 carat white gold and diamonds. The oval-shaped Paraibas, which weigh 0.78 carats, sit inside a diamond-shaped setting that has elegant openwork at the back. There are a total of 32 D-colour flawless diamonds packed onto these earrings, which are secured at the back by a pair of solid gold butterflies. These rare gems, set into a clean and simple design, create a timeless classic that will bring a touch of luxury to the everyday.
