This is The Moon. Its double sided with a different array of craters and bumps on both sides. Its made of solid silver and measures about 55mm across. I'm wearing it with a pretty casual outfit but it also looks amazing with a shirt or frock... basically it's a bit of a show stopper.
Its part of an outer space space series that I'm doing about planets, moons, meteorites andnear misses. Have a look at some of the other members of the collection if you are interested, they're quite fun.
