Vintage very old silver ring handmade

It's about a size 6. It's marked with the makers name. It's silver and I think it's either bone or ivory. I got it about 10 years ago I can't find the card from the person I got it from at this moment. But it's a nice ring and very unique especially to be sitting in my box. Maybe your looking for something that your grandma or mom might like or even yourself. I've only wore it for a day then put it up. I planned on getting it appraised I just never got around to it so I don't know what this ring is worth. I'm selling it for what I got it for. I'm sure it's worth a lot more. It probably could use a cleaning but I don't want to ruin it especially with how old it is. I think it's from the 30/40/50/60s maybe or even older I'm just guessing. If I have a chance to get it apprised by a jeweler then I'll fix the listing.
