Fools Gold maybe

Hi. I found this on the beach this morning, it is black, but feels softer than rock, possibly charcoal or something. It has seams of sparkly gold in it. Can I retire off this?

Many thanks

    Might be coalified wood, partly pyritized (yes - fool's gold), and including some pebbles.

    Would need to study under a microscope really - to get a good ID on the minerals and textures, upon which to base an overall ID.    

     

    Other opinions needed...

      I agree fools gold a Pyrite in  the first picture in the lower half I think there is the edge of a calcite shell, possibly the body of your find is a mud Shale I found similiar lumps in the Severn river at Hock Cliff just above the Sharpness Canal Triassic (if my memory 35 years back is correct ) but they often contained Ammonite fossils

          Robin,

           

          I would say 'yes', carefully. The point of a dart (as in pub darts) can be good to pick/prise away at such objects. Reserve a hammer for less delicate specimens! Also consider using  vice. The gradually-imposed force from a vice can be adequate to crack a rock - and without the smithereening that could ensure if you used a hammer to do the same thing!
