Many of the items appear to be jade/ jadeite/ or nephrite. The large heavy pig and the S- shaped bird/dragon items very heavy. These both have a crack that may have occurred from aging but they seem to be repaired well. I do not know who made any of them. I acquired them over the last 30 years from various estate auctions and antique stores. Please let me know if you require any more photos....some items can really only be photographed front and back.
The dimensions for all vary, but are described on each of the photos
