Penberthy Croft mine at St. Hilary in Cornwall, England, certainly ranks right up there as one of the most popular localities amongst collectors of Cornish minerals. This is probably because of its extensive list of recorded species (110), type locality to three and at one time, between the 1980s and 90s, providing a treasure trove of colourful specimens for those brave enough to enter its rather precarious stopes, then a riot of vividly colourful minerals lining the walls! These halcyon days are now ended as these sections of Penberthy Croft have now collapsed or are too dangerous to entre. For those not that familiar with Cornish geography, the tiny village of St Hilary lies about 3.5 km NWW of Marazion and St Michael’s Mount. Bayldonite is one of the type locality species mentioned and this is a super-rich, small cabinet specimen with bubbly, botryoidal druses of dark green Bayldonite covering and internally pervading a highly porous matrix of a granular, finely brecciated and iron stained milky Quartz. The specimen comes with a M.G.H (Mike) Merry (Truro) label featuring an engine house chimney, a label from his early dealership days and a rare item itself!
