This is a great ring. It is hallmarked “Silver”. I have tested the metal and it is sterling. The rose quartz stone is large and a beautiful pink color. The ring is adjustable so it can fit multiple sizes. It is currently at a size 5. The rose Quartz measures 20mm X 15mm oval. With a loupe I see amazing natural inclusions of crystals. You can see this in my photos. On the underside are 2 drilled small holes–I have no idea why they are there. The ring weighs 6grms. I would date this fine ring at c1950′s-60′s.
