It appears this brand is collectible. I have no idea re values, but some serious google time might reaveal some info. You might want to spend some time on https://www.925-1000.com/, which specializes in sterling silver. It’s a very informative site, and it also has a question and answer forum.
Your ring does have the clean lines that sermed to be one of this company’s signature looks.
