Unfortunately, what you have is a collection of beads that have been strung together by a previous owner. They are not all Chinese, since some are Japanese. It is certainly not a
"Court necklace." Since it has no integrity as an historical necklace, you can do with it whatever pleases you.

I'm on my way out the door, but I can try to answer specific material questions when I return, perhaps tomorrow.

Remember, very few actual Mandarin Court necklaces still exist. Many or most of the constructions so-repped are actually just made up from parts (in China) to be sold as authentic, though they are not.

I hope you are not disappointed.
