A Collection Share

As I only started collecting jewellery this year, and it's nearing the end of the year, I would share some of my collection. I don't follow any particular style or designer; I tend to just buy what I like the look of, and recently have been enjoying picking up odd, quirky pieces.
My favourite items to collect are brooches and bangles, but I've also got a fairly decent amount of horn, bone, amber, and coral necklaces.
Here are a few brooches though. These are my oldest looking pieces, and a couple of them are in a bad state of repair but I like them anyway.
I don't know much about any of them so any input would be welcomed.
Thanks for looking,
