A very striking and unusual statement ring, made for two fingers on a silver tone band and large diamond red stone with diamond shaped grooves. It's likely this ring is from the 80s / 90s.
A stunning  piece that would be great for a statement look or make a great gift.
In very good vintage condition, however as with all vintage items, some signs of cosmetic wear should be expected. Please see photos for full details.
The largest hoop sizes at R 1/2 - the one next to it is size P 1/2
