Ornaments from around 1900.

These belonged to my Gran, were passed down to my Mum and now to me. My Gran may have got them from her Mother as far as I know. There is no makers mark or anything and they are a little worse for the passing of time. They are quite heavy so I do not know if they are some type of pottery?
They bring back memories of my Gran and looking at them in her glass display cabinet as a child.
I would love to know more about them. x
