Fabulous Vintage Goldtone Princess Ring, with a pull to expand adjustable ring back, (the squared back pulls out to make it bigger). I think at one time this was done for ladies with swollen knuckles. The stones are red, blue, amethyst, golden topaze, emerald marquise glass stones, with a large 1.5 ct cabochon sapphire in the top. There are markings inside the ring, it is a pat no 2961855...The ring is 1 inch across, and the size is 7 closed, and 10-11 open. (There is one piece of the goldtone missing on the back of the ring, that is hardly noticable, but I want to disclose it, and it is priced accordingly)The ring is stunning on.
