A lustrous, transparent unusually-blocky crystal of Kernite from the type locality, which is twinned on {011}. Kernite is a relatively rare hydrated Na-borate hydroxide with perfect cleavage and a brittle fracture. There are some small amount of white surface alteration (via dehydration) to Tincalconite, but limited by a coating of plastic spray. The crystal ends are matrix influenced, as typical. This is the only twinned crystal I have seen from this locality, which is all but closed to collecting.Data last checked on 28th Jul 2024 - specimen may no longer be available
