Thanks Danny & Floor - I scratched all three beads with a common pin (the kind used for sewing) and all three seemed to scratch the same. I could see scratch marks easily using my 10X microscope. Very hard to say if the $8 bead scratched more easily than the other two.

If they scratched none are Nephrite or Jadeite. (no text) --- lopacki ( 2014-09-10 17:02 )
