Anyone know what on Earth I found? An Antique Chinese Jade Ivory Necklace?

so this was at the bottom of a jewelry jar and I must admit, I’m confused if I should get this appraised or not.

I can tell it’s real jade (the chinese dragon carving) and real obsidian/onyx and the tiny beads are real Malachite. I’m unsure what everything else is and what i actually have here.

Any thoughts on what time period this is from, what it is, etc?
