Ceruleite

/sɛˈruːliːaɪt/ noun

Definition

A rare blue copper oxide mineral found in arid environments, prized by collectors and historically used in pigments.

Etymology

From Latin 'caeruleus' meaning blue, combined with the mineralogical suffix '-ite' denoting a mineral. The name directly references the mineral's striking blue coloration.

Kelly Says

This gorgeous blue mineral contains the same Latin root as 'cerulean'—ancient Romans saw the color of the sky and sea, and that very word traveled through centuries to name a modern mineral discovery!
