If I may give a little more input on a couple and see if you can better identify the ones w/ ?s.
No. 2 is a kind of yellowey brown color and is kind of cloudy, but you can see light through it. It has those cracks shown in the picture on the one side but is very smooth, like glass. Very unlike no. 4 which you identified as Jasper (which I agree I'm sure I've seen it before somewhere)
No.3 is very similar to No.2 in that it is smooth and light shines through (like smokey glass) but is a little darker w/ a kind of purple hue. It has one crack that is green and several that are brown
No. 13 is a very deep purple color w/ some white cracks and speckles
No. 14 is a dark brown w/ light brown and white stripes in it
No. 16 looks black around the outside but in the middle it is kind of an opaque brown color
No. 20 is a kind of sparkley black but not as shiney as the others
Thank you so much for your input you are brilliant :smt003 I will enjoy looking up some info on these now.
Best wishes
Louise
