Known for its unique colour spectrum, tourmalines are one of a kind. In an Egyptian legend, the semi-precious stone is believed to elapse over a rainbow – earning the nickname “gemstone of the rainbow”. However, here STYLE presents five majestic jewellery pieces that will make you green with envy – with the colours of regal green and mesmerising blue, just like Kate Middleton did with her green tourmaline and green amethyst oval drop earrings. Plus, we included the notable Paraiba tourmaline, a spectacular sight which is one of the rarest and sought-after gemstones in the world. Van Cleef & Arpels Inspired by the ocean blue, the Beauté Nocturne necklace boasts one tourmaline of 39.78 carats, round diamonds, blue and purple round sapphires and black opal beads.
