Many thanks for your replies. It was found about 10 miles inland. There appear to be some small crystalline objects embedded in it, and a larger red/brown crystalline substance visible on one side (bottom of second photo).
Hello All. Would someone be able to help me identify this object please? Found during a walk in the New Forest in S England. No other similar objects nearby. It's clearly metallic, deflects a compass needle, and is strongly attracted to magnets. Density is around 6-8 g/cm3. I suspect it's a just a piece of rusty old man-made iron, but wanted to check with others. I filed a little off one end to expose the shiny metal. Many thanks.
