Charms

Collect them one at a time. Twenty-seven charms in solid 14K gold — four-leaf clovers and artist palettes in fired enamel, diamond-set arrows, letters, symbols. They clip onto a pushlock or any chain you already own, which makes them the thing to buy when you want to mark something without buying a whole necklace. Add as you go. A chain carrying six charms took years to build, and looks like it.
