The stone is solid: cobalt lapis lazuli with lighter clouds and dots of pyrite. The rectangular shape maintains discipline, and the color does the rest.

The ring is openwork, with "architectural" cutouts, giving the ring weight without being overwhelming. The lugs aren't perfect – they're meant to look handmade, because they are.

With white and navy blue – it's stunning. With black – it's very elegant. This isn't a gadget, it's a wardrobe staple.

Heavy, patinated silver. The ring has a history and doesn't pretend to be brand new.
