Description
Large Rainbow-coloured Carborundum Crystal Display Specimen
A large cluster of silicon carbide showing beautiful iridescence. 1 kg, 16 cm (6 1/4 in.). [No Reserve]
From the private collection of Kenneth Machin (1936-2020), Buckinghamshire, UK; his collection of antiquities and natural history was formed since 1948; thence by descent.
Carborundum rarely occurs in nature, but is commercially formed by heating carbon and silicon at very high temperatures, producing extremely strong bands of crystals.
