At the centre of this Kat Florence ring is an elegant pear-shaped Paraiba tourmaline. This vivid gemstone, which weighs in at 1.13 carats, was mined in Brazil, the birthplace of Paraiba tourmalines, which makes it extremely rare as the mines where the original Paraiba gems were discovered are nearly depleted. The Paraiba tourmaline has been put on display in an 18 carat yellow gold ring studded with 0.93 carats diamonds. The diamonds selected are all D-colour flawless stones, which ensures they deliver an incredible sparkle. A secret component of this ring is a flexible gold spring on the inside of the shank that keeps the ring secure and upright on the finger, but also allows the ring to fit up to three finger sizes so you can wear it on multiple fingers.
