I got this piece of burl in a lopsided trade with my friend Mark Cothren (I got the better deal). I've never turned Amboyna before but I assure you I will turn it again. Wonderful wood. This box measures 3-1/4" dia. x 3-1/4" to the top of the ebony knob. Walls 1/8". Finished with antique oil and buffed.
