alexandrite singular

alexandrites plural

Morphology

alexandrite = Alexander (opaque) = Alexander + ite

Formed from the proper name 'Alexander' plus the mineral-forming suffix '-ite'; the name-based derivation does not allow learners to infer the gemstone's specific properties (green chrysoberyl that changes colour).

Etymology

Alexandrite was named for the Russian prince Alexander after the stone was found in Russia when he became a young leader. People noticed the gem could change from 'green' in daylight to 'red' in lamp light, so alexandrite now means the rare gemstone that changes color.
