Vintage enamel style pendant- barely worn!

This is costume, but the rose is so pretty- I don't wear yellow gold ever, so I'm trying to weed out my jewelry. I love the domed glass look. My mother in law was the original owner, I'm the second. She didn't wear it much- this is pretty much mint. Marked Western Germany. Update: this was purchased off-site & returned. Added travel, no added wear.
