The Machinist is a handmade titanium ring engineered for those who appreciate raw, structural beauty and an unmistakable industrial character. This striking titanium and carbon ring with brass inlay bridges engineering and art, with a sleek, hypoallergenic profile and the option for a free engraving. The band splits its personality in two, one half showing the deep, organic swirls of dark forged carbon fiber, the other the clean, brushed texture of solid titanium, divided by a precision line of warm brass.
