Alberon porcelain doll - Clare (limited edition)

Hello,
I have a nice Alberon porcelain doll. I don't know how rare is it, but I didn't find the same doll on the internet. Does anyone have an idea of the value of this doll? I don't have a certificate, but it's in the original box.
I know this doll is an individually numbered limited edition of 2500 pcs worldwide.

Any help would be great.

Thank you :)
