Hobe Demi Parure

This is a demi parure that belonged to my grandmother, I inherited these pieces several years ago. I do remember my grandmother often wearing this set. It is signed Hobe. I had the necklace restrung because all of the stones were off the string. It also has a new clasp.

Let me know what you think of this demi, I havent seen one like this before ?

Would also again like to know the value, year produced, any info you have to share ?
