I have found apatite to be particularly responsive in matters of ancestral work. While I haven't found so far any literature to support it and this claim is based on my personal experience, it might be interesting to try if that is something that you're curious, or even seasoned about. 
 
This listing is for the specific pendulum shown in the picture.
