I bought this for a friend thinking it was a jade. It was advertised on amazon as a jade. She got it and it said in the paper she got with her package that it was an "adventurine". I looked in my recent orders and sure enough the description had changed to "adveturine". It is still really pretty and if nothing in the description had changed i would have still thought it was jade. other then that I am happy because my friend loves it.
