Antique 14k/platinum rings - $1 (Rapid)

I collected two-tone antique fine jewelry for years and have lost interest.
These are a combination of yellow and white gold and yellow gold and platinum with real diamonds.
They are all pre-1920 and range from size 6-7.
Prongs have been maintained.
I would prefer to sell them as a lot and would consider trading for something interesting with/without partial cash.
