Ring with pink and green gemstones - glass?

[MetalIsland]

I found this ring about 6 inches deep in the soil close to a freshwater lake on an island in the Pacific NW.

Not exactly sure where it's from as it seems to be a hodge podge of styles.
French - Nouveau looking piece, leaves with grapes??
Says 925 on a stamp inside with ERZEU or ERZEN but may not be the whole stamp too...

Americans visited this island in earlier years of the 1900s.
Also on exploration route of Spanish explorers, but may not be that old.

3 photos - top, side, and inside.

Thanks for any suggestions! Cheers.
