Many Vintage Pieces with no Knowledge of Age or Worth,?

Hello, recently my sister and i were cleaning out my grandfather's house which is planned on being sold and i came across 3 small sized metal boxes that had what i assumed is vintage or antique costume jewelry.

My grandmother passed away 16 years ago and was a big fan of precious and semi-precious stones as well as quartz crystals and rocks and would always attend trade shows. To make a long story short, I'm not sure what any of the costume jewelry is worth or the age of said jewelry what so ever and I want to know what I have.

If anyone is willing to take a little time to share their insight with me that would be great and, I would be so appreciative!! I have no problem uploading pictures of all the pieces. Thank-you for taking the time to read this and hopefully someone will be willing to help.
