This is a collection of vintage jewelry that is unmarked. The collection was given to me as part of my inheritance. My dad passed away this year and my Mom wanted me to have this before something happened to her. I am a photographer/artist by trade so I don't know a great deal about vintage jewelry. This is a 40 year collection and some has been in storage for more than 30 years. Any help identifying the pieces would be deeply appreciated. Thank you in advance.
