With over 30 years of knowledge and experience under her belt, gemstone expert Joanna Hardy has captured her craft with the release of the second edition to its The King of Gems series. Aptly titled Ruby, the new visual read features coveted designs of the ruby stone, crafted into jewellery pieces by sixty of the world's most luxury brands — think Cartier, Van Cleef & Arpels and Bulgari. Commissioned by Gemfields, the London-based mining company digests the history and making-of the ruby gem pieces, including exclusive images from royal and private collections.
