John Cornish

Special guest

Mr. John Cornish is a consummate field-collector and miner. John is based out of the Pacific Northwest of America and is only truly happy when he's mining and digging specimens or when he's baking freshly picked wild-berry pies. John's enthusiasm for mineral collecting comes out most obviously when he's giving presentations to kids and, honestly, there is probably no one in the mineral world who has given more presentations to kids than John himself.
