Help ID’ing silver jewelry

My wife wants me to put these pieces of silver on ebay. Two with no marks and one with a stamp on both ends of the bracelet. I need help with terminology to use in listing and possible identification.

1st set she bought in an antique store in Armenia around 20 years ago. Well not speaking the language, she believes it was an antique store. With no marking, I personally like the lock of the earrings aside from them being gorgeous. My eyes aren’t as good as they use to be and I almost broke them trying to open it. It just takes a slight upward push and pop, they’re open. The hole for the hook looks like it was cut with a knife, A very very tiny knife . Well hope someone has been to Armenia and can recognize these.

2nd set was given to her from the boss of her then be it boyfriend. He worked for the American Consulate in China(very glad he had a good eye for women, but after he got her approved for a 2year multiple visa, while in North Carolina, she discovered he also had a wife and another girlfriend, lucky me.

3rd was purchased and given to her from her first husband(American) while they were in Egypt. This one has a mark at both ends. Again hoping someone can decipher it. Extremely hard to get a clear picture.

4th item(stone in pendent) is not going on ebay as she loves the stone and it a keeper for her, but would love to know what type of stone if possible.

again please throw out any term I can use. It is very helpful to me
Thanks

 

The mark that looks like . . V is an Egyptian 800 silver mark, upside down. The mark next to it looks like it could be an incomplete date letter. Probably for around the time the bracelet was acquired.

 

I don't see anything really old. The filigrees with the red stones may be Armenian, but I agree the bracelet looks to have Egyptian marks. The bottom one is an agate. Not sure what the purple and white ones are. Or where from.

 

#2 agate with quartz.

 

Blue may be Persian or Afghan turquoise.

 

I'd bet on it being glass from here, with hopes of being proved wrong.
