Exploring the blurred line between masculine and feminine, Hannah Martin designs fine jewellery for men that women covet and love to borrow. The Hannah Martin It's Only Rock n' Roll collection seeks to explore the sharp and brutal nature of this genre. Things are not what they seem, stones are set upside down and precious metals are hidden behind a black exterior. Hannah Martin's It's Only Rock n' Roll studded ring is accented with reversed diamond-cut sapphires, set into a yellow gold band. The yellow gold is concealed beneath a treatment of black rhodium, and the band appears to hover on the finger thanks to a knife-edge that runs around the inner circumference of the ring.
