. A group of exceptionally large rose quartz crystals accompanied by several smoky quartz sceptre crystals, from Minas Gerais, Brazil, with Dr M. G. 'Sam' Weller, MBE, collection label; Dr Bonewitz notes: 'Rose quartz crystals are almost always tiny, and seldom reach 3mm. There are crystals in this group that are twice that size'.

'Sam' Weller, MBE, collection, Cornwall, UK; from Coronal Mountains, Minas Gerias, Brazil. 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. [No Reserve]
