Sterling rings deco? etc. hodge podge!

I once bought about 275 gms. of mixed sterling jewelry, I separated what I thought was the best, and these rings are kind of leftovers, they are ok but other items were Mexico, and Europe and East Asia, these just say 925 or sterling, The big ring with all the glass? I assume it is glass, why would someone take the time to cut the glass that many times? over bling!!! I do not have a clue what the red stones are, and 2nd ring on bottom, the top spins quite fast, maybe for nervous people! 3rd ring with red stone looks like two diamond or glass chips, and has gold wash. Any help would be appreciated. I have over 9 pounds of sterling jewelry. I still think it is better than 1% CD's. Now I am buying more vintage gold. Tomorrow I will post gold rings that confuse me like these! haha Again thanks for looking. I am kind of stuck. I have collected for over 35 years but now I am disabled Vietnam Vet, and not allowed to work or make money? I was shot but at age 55 agent orange screwed up my legs some. I can not complain with 4 retirements, but I should be allowed to sell things I bought years ago! Thanks for looking! any help is appreciated! I do not know if art deco is right for some of these?
