I have never seen this pattern but there were genuine private purchase Third Reich rings that were quite unique. However, without a clear period photo of someone in an SS uniform wearing it or excellent provenance, it is impossible to tell if this is a genuine, private purchase ring from the Third Reich or if it is a postwar item.
It is a nice ring, and I have seen shanks with a similar Art Deco design. Nevertheless, personally, I would not touch it without clear evidence that it is from the period. If this ring is from the same source as the monstrosity that you posted last week (

I have a couple of SS rings that I hope are from the Third Reich, but my hope is based largely on trusting reputable, known sources. I no longer buy any private purchase so-called 'SS' rings because they are so heavily faked or fantasy pieces. There are known patterns of SS rings but these, too, are widely faked unfortunately.
Interested to see what other, more knowledgable folks think...
Cheers,
