This is an artist made bottle stopper. It is 4" long and has 1" of tapered cork, wrapped in a a brass blanket, open in the front. The wide, rolled opening is fitted with two tumbled natural stones. The larger is an amethyst, and the smaller, on top and behind, is rose quartz. These stones both have magical properties. The purple amethyst was actually used by the Romans to prevent drunkenness. Perhaps that is why it is prominent in this bottle stopper. Please look at the photos to see detail on this item. It has to be one of a kind.
