Not a fossil, but a nice piece with quartz or calcite crystals. To tell which it is you can find an inconspicuous place to scratch or drop an acid (vinegar is ok, I find lemon juice sometimes works better). Calcite will scratch or fizz, quartz will not. Sometimes it’s easier to hear it fizzing than see it.
if you don’t have any of that available, you could scratch with a steel pin/nail, if It scratches then it is calcite, if it doesn’t scratch then quartz as that has a moh hardness scale of 7
Ok thanks Corinne and Ben
