Hobe Demi Parure with Mink

This is a beautiful Hobe Demi Parure, thought I would share ! I inherited these pieces from my grandmother. I do remember her wearing this on special occasions. It is pretty, and old ! It has a long necklace, one set of long clip earrings, it does have mink accents ! should have another set of clip on round earrings however, one of them has been lost (by my grandmother) I suppose on one of her party nights ! lol

It is signed Hobe.

Would like to know the value of this demi parure ? the condition is fair, and one of the clip round earrings is missing :( What is the proper way to store this parure ?
