Definition

Meaning

A precious stone, a deep orange-red variety of chalcedony.

Historically, a term used in Biblical and ancient contexts (e.g., Exodus 28:17) to describe a gemstone, often associated with the modern carnelian, used in high priestly garments and as a symbol of divine attributes.

Linguistics

Semantic Notes

The term is largely obsolete in modern everyday English. Its primary contemporary use is in discussions of ancient texts, historical gemology, or in poetic/literary evocations of antiquity. It is not a term for a modern, commercially traded gemstone.
