This is such a beautiful ring, and it comes from one of my favorite periods of antique jewelry--the 1840's. We have a foiled amethyst, with a natural pearl surround. There are pearls on the shoulders, and the shank is beautifully chased. The ring is a size 7, and is in excellent condition. The top of the ring, with the amethyst and pearls, measures 3/8 of an inch North to South, and a little over 1/2 an inch, East to West, not counting the three little pearls on the shoulders. It is crafted of unmarked, but tested, 18 ct gold, and is a beauty.
