Pressed moonstone glass earrings

Any idea on who or when? The pale blue of the cameo is the blue of the glass. You know the way light plays across moonstone (impossible to catch in a still photo). The dark blue ground is applied color and there are losses to it. Does that kill any interest? In addition, one of those post retainers obviously doesn't belong. How bad is that? They're small: about 3/4" by 1/2". No maker's mark.

 

These could be a craft kit item, or from two blokes in the proverbial shed. Some craft show items were made that way right out of the box. They were never valuable even brand new, and they probably aren't worth much now.

 

I didn't know that they made craft kits for this kind of stuff. They are what they are. Thanks for looking.
