Not long ago, cufflinks were a gift quickly stuffed in a drawer and forgotten about. However, in recent years, sartorial style has gone full circle with the return of double-cuff shirts, which means that cufflinks are completely covetable once again. London-based jewellery designer Hannah Martin has taken the humble cufflink and sent it on a space odyssey. Embracing the dark side, her Onyx & Sapphire Orbit Cufflinks feature mysterious black orbs, encircled by a planetary ring of gemstones. Handmade in London from 18ct white gold, sapphires and black rhodium, Martin's celestial Onyx & Sapphire Orbit Cufflinks are the best-looking cufflinks we've seen all year.
