I worked late, and then just kind of crashed on the sofa in front of the TV, pinning tiaras to a couple of period boards: Regency and 1860s. It should be helpful as I start to narrow down my own selections for costume use.
It's a shame tiaras weren't much of a thing before then, since my other major costume period is 1780s. The major jewel item seems to have been the devant de corsage or stomacher, meaning a jewel worn in the stomacher position. Every so often you can find a giant brooch with the right shape, particularly triangular, and better if it has danglies. I know
vanessa_lynne and
starlightmasque at least have one...
