I really want one but don't know what jewelry/item they will take.

I think they accept items from the glittery shop. I fed this item: and got accepted.

I'm pretty sure anything from the store All That Glitters. I had about eight items from that store and they all were useable.

i tried the same item and he dont accept

: Maybe they shuffle the required items. I don't know, but I adopted one. If you want one just send me the name and gender you want and I'll try out. I have a few glittery items in my account.

Thanks, guys. I'll try a few things out and see if they work. EDIT: I just picked the cheapest item I could find from All That Glitters and it worked for me.
