Copper Pave Pin

This is a beautiful UNSIGNED pin and I am trying to figure out its value and possible designer. I'm a newbie at collecting but this pin was so beautiful and was included as one of several "freebies" for other costume jewelry I bought. It measures 2-1/4 inches at the widest point and 1-1/2 inches in the middle. All of the copper stones are set in prongs. All but one of the rhinestones in the swirls is intact and tight. There is a very large copper jewel in the middle and this is enhanced by a dozen small round copper jewels. Peeking in between the swirls are three large rounds as well and this design is by the "leaf" jewels which bring the design to a point.
Pristene shape except for that one small rhinestone which I think can be easily repaired. Just gorgeous - the cuts on the stones make it sparkle from every angle! History and value would be greatly appreciated.
