Antonio has done his homework and research.. The info on the runes are in the book but are not from his personally looking at the credits. The info is from his research....

Evgeniy on the other hand is correct also in his opinion.... It all comes down to this though.. Is it possible a period jeweler to have installed the eyes? well,,,yes.. BUT,,is it probable?... Possible,,probable...........

My opinion is period jewelers wouldn't want to even resize a HR let alone add something to it...

I too like Mikee wonder what those eyes are! Glass? ,Garrnet?[no] , Ruby? As on the Fundforum my advice to the owner is,,,leave it be as is...
