Featured Can I have help dating this Egyptian Akhenaton ring? TYIA pic heavy

Hi!
This tested as silver but unknown purity. The only other I find is much fancier on the interior and 18k white gold. Any ideas on the maker, age, or anything else about it? The blackening looks to have been done on purpose to me but then WTHDIK?

Opinions, please and thank you

 

Looks like a poor casting full of porosity,could be someone's attempt to copy an original piece.

ya, funky ring....likely silver.......poor casting !!

at least someone took the time to mark it...........

 

Like the 18k one. Ok, makes sense. Ty

 

Looks like the marks are part of the casting, so it never saw the inside of an assay office. Even if you could read the marks, they would only indicate the age of the original, not of this copy.
Fun ring though.

 

Gee, that's wild!
Egyptian meets brutalist!

 

Weird, right?? Lol
