Tomasz Donocik / Trash Design Manufactury

Tomasz Donocik has a flair for the dramatic. The London-based Austrian jeweller gives his nod to old-world decadence, resulting in fabulous pieces like the silver tower ring, above. Below are his pentagon "star" ring in gold and quartz and the leather ball "tree ring," for wearing betwixt the fingers.
