Cerargyrite

/səˈrɑːrdʒɪraɪt/ noun

Definition

A mineral composed of silver chloride, historically important as an ore of silver and also known as horn silver due to its horn-like appearance.

Etymology

From Latin 'cera' (wax) combined with 'argyrite' (from Greek 'argyros' meaning silver), referring to its waxy luster. The name describes the mineral's wax-like, horn-like translucent quality.

Kelly Says

Cerargyrite literally looks like pieces of translucent horn or wax when you hold it up to light, and it's so soft you can cut it with a knife—miners in the 1800s thought it was amazing that such fragile-looking material contained valuable silver!
