I am rather excited about this rock found at east coast of England. The colors are pink and whiteish, it is dull when dry. But if you hold it against light, the pinky part let more light through. There is a hole at the side, it has little lumps in it. Could it be a agate? Thanks for help.
Looks like the mineral agate chalcedony to me, that's a nodule, "the little lumps" is botryoidal chalcedony, you should polish it up, its beautiful, nice find
