CZ round solitaire rings four 4 nice as-is or harvest stones for new settings

Four (4) rings each with large center round prong-set CZ/glass solitaire + 2 have channel-set rounds on side band + 1 has rectangle-shaped stones channel-set + 1 is just the solitaire. Sizes are between 7 and 8. Settings are all tight but two have so much wear to silver-tone on the surface that copper has come through. Of the other 2, the 1 with gold-tone metal accent alongside says "Thailand" on the inside; the other inside says "CZ" and "925 China". They are kind of nice as-is or the stones could be removed and placed into new settings. Ships from a home with cats.
