Find this ring's twin!...or at least it's cousin

[Bellyd]

Has anyone seen a ring similar to this one? I've searched the internet for a while and I can't find anything that looks like it. It is Platinum, and the stamp reads '10% irid plat', which I have learned could possibly mean it dates 1890s to 1930s. ANY info and/or links to photos would be appreciated.

Style-wise this might be a cousin with a couple of similar elements viewed top down. Side view is very different though:

It’s really hard to tell from the photos, but to me it looks like an 1980s to 1990s style cluster ring
