Corundum: Ruby and Sapphire
Reinhard Brauns, 1903
reproductionpre1931-platerights: pending
A chromolithograph sets ruby against sapphire across a field of rough crystal and cut fire - the two faces of a single mineral.
Why it matters
The plate that taught a lay public that ruby and sapphire are one stone, corundum, wearing two colors.
Notice
The pigeon-blood red and the cornflower blue, drawn from the same crystal family, laid side by side.
Meaning
One substance, two fates, decided by a trace of chromium.
