1st gold ring?

[hlewis1007]

Its an initial ring with "P" inscribed on the front with a few designs on the sides.It broke while cleaning it up but the band inside
says "gold SH?" with 3 diamonds stamped in there..i dont know if there was anything else wrote inside the pieces were lost.
Any input or thought welcome.It should be atleast gold plated.I hope.

I am missing part of the band it could have very well spelled shell out..idk

That ring is gold shell, it has a shell of gold around a brass core. Shelled rings have thicker gold than gold plated rings. GS = GOLD SHELL, HGS = HEAVY GOLD SHELL. If it aint marked k, its not a solid ring.
