Here is wonderful vintage ring which comes from the 1940's and is part of the early Mexico jewelry movement. It has a large cut Amethyst in the setting. It is a gemstone, but I cannot tell if it is synthetic or natural. Whichever it is, it is a gorgeous stone and very nicely cut. It is reminiscent to me of the the rings by the famous Mexican Taxco artist Faus, because of the styling of the ring. It is marked on the inside with the initials "JS" and under it .925, also it is marked with a bell shaped mark right next to these other markings. It is a size 5 1/2 ring. It is a great looking ring.
