Etsy Seller Amy Moore's shop Honey Bee has wonderful silver jewelry made in natural forms: a maple seed, a sea urchin's nubbly surface, the texture of a leaf of sage, weathered wood grain. These are good things to wear when you work in an office without windows. When you don't see the outside except when it is dark. When you're about to forget how green things look. Other than that, simple natural shapes make for lovely adornment.
