Burmese Ivory Figures

There are several  types of ivory, elephant, walrus, and mammoth ivory, then you have carved bone as well.  It is impossible to say what you have unless you can take them to a jeweler or Asian expert, to test them or look at the grain under a high resolution microscope.  Many items marketted as Ivory, weren't, so its best to rely on the experts.  If they are ivory, they are a nice size and at auction would start at $500 each and go up from there depending on the crowd.  If bone, far less.
