A letter that means something, hung beside a single diamond. Wear the initial on its own, the diamond on its own, or both together, which makes it three necklaces and one decision. It is the piece people buy to mark something, and the one they stop taking off afterwards.

An oval laid on its side, resting along the collarbone rather than hanging from it. The boldest single stone idyl makes, and the one that does not need a second piece to be the whole look. It lifts off the chain and onto a hoop whenever you want it to, though most people leave it exactly where it is.

A single round diamond sitting in the hollow of the throat, the cut that has flattered everyone it has ever been put on. Set so it holds more light than its size suggests. This is the one you reach for when you have stopped wanting to decide what to wear. It moves to an earring on the days you want it to.
