How Much is that Necklace in the Window?

I went by Finders Keepers in Decatur, Georgia a couple of weeks ago and was so happy to see one of my necklaces on a mannequin in the window.  

The necklace is a one-of-a-kind piece of costume jewelry.   The ring is glass and the chain is aluminum.  Here is a close up shot of the necklace.

I love making costume jewelry - especially when it is one-of-a-kind.   I was so happy to see the necklace in the window, 

I had to take another shot of it as I was pulling out of the parking lot. (You can see the reflection of my white car in the store window.)
