Vol./W^3 = 0.796



Addition # 14 - This is a very nice long bead. It works well in about any material. Note that the crown and pavilion are the same. A table can be cut at C6, P6, but I usually do not bother. Just use a ball burr and concave the ends slightly so that a bead spacer will fit in and protect the ends.
