1887 H. C. Lewis in Papers on the Diamond (1897) 50 There appears to be no named rock-type having at once the composition and structure of the Kimberley rock... It is now proposed to name the rock Kimberlite... Kimberlite is a rock sui generis, dissimilar to any other known species.
1899 Edinb. Rev. Apr. 319 This ‘blue’ rock—named ‘Kimberlite’ by Professor Carvill Lewis—is really of a dull green tint, due to its impregnation with iron oxides.
