Jeweler Career?

I really hope so, both as a career and as a skill. (Like Flower Arranging/Gardening Career in Seasons) You could make accessories like the buyable ones in Bon Voyage, or display them in cases. For the career, item unlocks could be jeweler's furniture/cases to use in your own store.

Currently, I have a "jewelry store" as part of a retail lot, but it is just decoration. I used the cut gemstones from Seasons and put them on shelves behind a counter.
