Where can I find concho pendants with rhinestones?

I’m looking to start making chunky/ western necklaces you would likely see at cattle shows. I have looked around and I am seeing concho pendants with rhinestones. I’ve googled for places to buy them at a very cheap price and have had no luck finding what I’m looking for. Any ideas on how to make them as well. Thanks
