Scratch order from talc to diamond

The Mohs hardness scale ranks minerals by scratch resistance on an ordinal list of ten reference minerals, from talc at 1 to diamond at 10, where any mineral can scratch those below it and be scratched by those above. Klein and Dutrow's The manual of mineral science presents it as a standard field and laboratory diagnostic, noting that the steps are unequal: the jump from corundum (9) to diamond (10) is far larger than the lower steps. The construct is a comparative, non-linear hardness ordering used to identify minerals and gems, not an absolute measure of hardness in physical units.[1]

Unit
An ordinal position from 1 (talc) to 10 (diamond) on the scratch scale
Recovery means
Not applicable
Measured by
Determined by which reference minerals a specimen can scratch and be scratched by
