Fibonacci gold ring with coloured gemstones

EDITOR'S REVIEW

Irishman Stuart McGrath, who set up fine jewellery brand Armoura at the end of 2015, is one of Ireland’s new contemporary fine jewellers. This Fibonacci Ring is typical of his adventurous designs, which are bold, colourful and unusual. Previously an award-winning sculptor, this spiky ring has a menacing look thanks to the reverse-set pyramid-cut coloured sapphires and rubies - 42 in total - set into an 18 carat gold band.
