Looking to identify maker

[rejd]

I just acquired this piece from a local thrift store. It is marked 333, which I know is 9c, but cant figure out the maker. It appears to start with KR OP???. I can't get a clear picture of the mark. I know this may be difficult but appreciate any help.
Thanks

Not enough there to go on -- could use a higher-res image.

Very pretty- may be Bohemian garnet?

333 gold is 8k

375 gold is 9k

If you search 8k Bohemian garnet, you may find additional information on the hallmarks of your piece.
There are quite a few examples of jewelry with this search.
