[QUOTE="Wally69, post: 434847, member: 1916"] Though I would start a new thread and ask a question that has prevented me from dropping a small yellow sapphire for fear of stuffing it up. The photo shows the cut and rough shape of the stone, so you can see why I chose this diagram. What is missing from the instructions I have is where to centre the dop needs to be situated on the long axis. I have marked where I am taking a wild guess but thinking the cuts will not produce the level girdle shown on the diagram as all faces are not symetrical around a single axis. Anyone had experience with one of these they would like to share?
