### Core Meaning & Semantic Range
The Hebrew word **kadkôd**, represented by `{{H3539}}`, refers to a **sparkling gem**, identified as an **agate** or possibly a ruby. Its name is derived from a term suggesting the striking of fire, implying a brilliant or fiery quality. This word appears **2 times** across **2 unique verses** in the Bible, used in contexts of great value and divine beautification.
