The width of the stone in ALL cutting instructions is the W dimension and that is on the 96/48 axis.
Dan Lynch has inadvertently thrown a big spanner in the works by saying it’s not with this stone and that it’s on the junction between girdle facets G4 and G5. Hope you don’t mind me saying Dan, that is also wrong. If you were to measure the stone in that direction the widest point is between the junction of G5 and G6.
Just a quick comment from the land of fire and smoke.
