Vintage 10K Black Hills Gold horseshoe/flower stick pin

I am selling a cute Black Hills Gold vintage stick pin. The head is a horseshoe with a little flower on it. The end screws off so you can pin it to whatever you’re wearing or want to affix it to. It’s a little over 2” long and weighs 1.47 grams. It’s marked 10K and something else but I can’t make out the makers mark. Please see all photos for more details.
