Estate find that I don't know much about.  It is black, but I'm unsure of the stone type, perhaps soapstone.  Many items in the home were purchases from travel/ vacations in the 70s-90s....maybe this fits in that time frame, but again I'm unsure.  It measures approximately 3" high x 2.5" x 2".  Condition is used but there are no chips, cracks or repairs.  Enlarge and look at all photos for more details on condition, design and size.  Please contact if additional information or photos are needed.
