if you look on ebay....you,ll find that 99% of ivory listed items have faux in the title...even although most of what is being sold..dates before 1947...which is the date that prohibits the sale of certain types of ivory..unless its certificated....hen ce the reason for saying its faux....that way you are not breaking any law...the prospective buyers will know if it is ivory or not.....it certainly looks like ivory....or it could be as has been mooted, ox bone, but it could also be walrus tusk...which has a later sell by date.... if it is your intention to sell it...you could try ebay....with either a fixed reserve....or if its not getting what you want for it..you can say it is also listed elswhere and you reserve the right to end the auction early....
