Yep, those look pretty darn good for costume jewelry.
I wouldn't let any of my kids get close to a horse with them on though.
I have broke a few dozen horses. I only found the need to don spurs for one, and she was a twenty year old spoiled schitless mare. One afternoon I decided she was going to have to learn who actually was the boss. Two hours later we were both lathered up and she had blood running down both sides of her ribs, but we had reached an understanding.
From that day forward, she was a pretty good cow pony.
