A mixed mineral group comprising: a chalcedony matrix with an amethyst surface, a lustrous combination of vanadenite, barytes and dolomite, a quartz specimen overgrown with yellow-brown botryoidal aggregates, and a very dark purple specimen of pyramidal amethyst crystal. 820 grams total, 62-100mm (2 1/2 - 4"). Ex Dr M. G. 'Sam' Weller, MBE, collection, Cornwall, UK, supplied with Dr Weller's personal collection labels or 'Henson, Knight, Weller Exchange List' label. Dr Maurice G. Weller, MBE, Ph.D, FISC, traded for many years as 'Sam Weller Minerals' following an interest held from the age of 12 years when he inherited a 19th century family collection; he was a member and sometime President of the Royal Geological Society of Cornwall and a member of Cornwall Archaeological Society (born Cornwall, 31 March 1931"). He had joined the RAF as a young man and spent 22 years in developing sophisticated military radar technology (for which he was awarded his MBE) until he medically retired in 1969, after which he established Yonder Town Field Studies Centre in Newquay, Cornwall before moving to Pendeen. Sam has now decided that the time has come to part with his private collection of minerals, including a number from historic Cornish sites, some with 19th century pedigrees. [4, No Reserve]
