Vintage Handmade Stained Glass Ring Gold Toned OOAK

One of a Kind Handmade Vintage ring with three circles of what I believe is glass set into a gold toned metal. There is one opalescent white one, one deep red, and one black. Band is adjustable but as is it's between size 6 and 7. Ring is large, about 1.5" at it's largest point and 1" the other way. The ring is shiny, but has some texture on it that looks a little like scratches, but considering they are on the back as well I think they are from what was used to polish it.
