i like hat pin.good spotting

Too optical for amber, and amber doesn’t survive in soil very well.
It’ll be cairngorm/citrine (basically a yellow amethyst).
Restore that one. Even if it’s getting a jeweller to do it, you’d be surprised how many people still shop for hat pins.
looks like a scots thistle too
