			Hello, 
		
		
		
			This is supposed to be a sperm whale tooth. Purchased from a seller who informed us that it came from tawi-tawi, from way way back. My plan, if indeed this is sperm whale tooth, is to use it as a pommel to an old barung or kris (which has no pommel). I've done some reading and this specimen conforms (in my unexpert opinion) to ivory. The ff are some things I have read on ivory's characteristics: a) ivory always has parallel grain, like rings on a tree or crosshatch pattern called Schreger lines. On closer inspection, this tooth has both parallel and crosshatch patters. b) in contrast to bone, ivory has a smooth feel. Thanks in advance for you inputs. Regards Yves  |
