2 vintage rings Sterling 1 with diamonds and moonstones

The first ring is a unique gorgeous moonstone flower the small diamonds around it make up the leafs did test positive as diamonds but the main stone in middle of flower I didn’t get a positive it may be still but can’t say for certain on that one. The flower petals look like white moonstones it’s a very pretty ring. I haven’t found another like it. The metal was tested as silver by whom I purchased from but I haven’t had time to test it myself and without a mark don’t wanna say sterling for certain but most likely is all the others were I got with it. Now The other ring is stunning Sterling Silver and is stamped 925 with simulated diamonds /CZ tested negative as real diamonds the sizes are in the pictures above on both Both in good vintage condition with only slight signs of ware/or age. Any questions please ask I do bundle for a small discount if multiple items just ask
