OK, here is what I found out in a simple test.
First pic is the antler before any testing.
Second pic is the antler after testing:

Quck dip in Cherry wood stain, 3 hour soak in cherry wood stain, last two are long soak in strong tea misture. Sorry, meant to have a short and a long soak, but got sidetracked and both sat for most of the day. I added the anterl after I turned off the heat but while the tea was still simmering.
I'm very surprzed by the lack of color the stain imparted, even after several hours. Likewise I'm pretty impressed with the effect of the tea and think it might look even better after buffing. All the pieces look better than they did to start with, but I still need to do the buffing step on all of them to see what the final results look like.
There you have it...
