This exquisite 'papillon' ring was designed in 2014 by London-based master jeweller G (Glenn Spiro) for Beyoncé Knowles-Carter.
The ring, in the shape of a butterfly, is an example of naturalism in contemporary fine jewellery and showcases Spiro's exquisite craftsmanship. Perched on the back of the finger as if poised for flight, an ingenious spring system enables the delicate titanium wings to gently 'flutter' with the movement of the wearer's hand. As the wings move, the vivid green tsavorites and diamonds sparkle intensely as they catch the light.
Spiro's atelier is housed in the mirror-lined rooms that once belonged to royal couturier Norman Hartnell, in London's Mayfair. Spiro is famed for his vibrant and technically superb designs and his passion for gemstones, which surfaced at the age of 15 when he was an apprentice at Cartier.
Gifted to the museum by Beyoncé, an international icon of the modern world, and one of the most successful music performers of all time, the ring joins a collection of jewels associated with some of history's most notable women including Elizabeth I, Catherine the Great and the Empress Josephine.
