This is a very rare genuine green Lucite ring with a yellow 10kt gold filled shank. The width of the ring is 8mm. I found this gem of a treasure among the lucite rings our  South Side of Chicago family jewelry store had left over in it's inventory and was not sold. What makes this ring unique and different from all the rest is it's yellow gold filled shank. I am happy to offer this wonderful blast from the past ring in sizes 6 and 8.
