Wrapped Pendant-5

Just bought a bunch of cabochons from my jewelry instructor. This was the smallest of them, measuring about 2 inches or so with the bail. I think the stone is a basic manmade stone, but I'm not sure how to tell. ^_^ Used gold-colored silver-plated wire, but I'm finding that the gold-coloring doesn't like to stay on, so it's slowly becoming two-tone.
