Featured Country of origin for this Victorian set

I posted this on the finds thread, not sure of country of origin. It is 14k, and there are hallmarks I can't read with any of my loupe on the pin stem. C clasp. I Google lensed the pieces, earrings seem to be Russian. Found for $6 with modern costume jewelry. Thank you.

PS: love the arrows and the crescents

 

Where are the marks on the brooch? The earrings looked Russian/Soviet to me before I went back & read that you said they were coming up that way. It's the expectation that you will put something square through a hole that is essentially round that gives it away.

The brooch/watch pin is beautifully made. Turn of the the 20th century; more Edwardian than Victorian. Unbelievable (but Oh how lucky!) that it was mistaken for costume. Have you tested pearls against your teeth? Perhaps seller's error here got it passed over.

 

The earrings go very well with the brooch, but I do not think they are a true set. Will be surprised if the brooch can be shown to be Russian.
