Vintage Miriam Haskell 3 piece brooch and earrings set

This is a very lovely 3 piece set, in good pre-owned condition.
This set is rare as well as vintage but I am unsure of the exact year. I was able to find pieces like these that were somewhat similar, in the early 60''s. If you are familiar with M. H. jewelry, you know that it can be and generally is, quite pricey. These may possibly be sterling (or ss plated) but I did not test them. These do show wear on the back but not bad. They will require cleaning and or polishing as I''m unsure how to properly clean them and would not want to harm them in any way. There are no missing gems and I did not see any cracks or chips in the blue moon shapes. I tried to take pictures in a couple different lightings but I feel like the blue you see is darker than it actually is (the last photo is more accurate..more like a dark sky blue).
As is, no returns.
Reasonable offers considered.
