925 Sterling Silver Smokey Quartz Ring Size 9

This elegant ring features a striking black gemstone set in a beautifully crafted silver band. Perfect for adding a touch of sophistication to any outfit. This has the famous RS makers mark, from what I have read online is confused as Ross Simmons but most likely Prime Art & Jewel. I can't confirm which. I think it is Rhodium plated. I did an acid test and confirmed silver. I am assuming the gemstone is Smokey Quartz (since Topaz doesn't actually come in the color Smokey, there is no such thing as a Smokey Topaz). Used but like new condition, size 9.
