Agate Slice A

An agate slice, specimen A — the stone sectioned and polished to reveal the concentric banding that gives agate its character. Each band marks a distinct period of mineral deposition within a cavity in volcanic rock, laid down over a span of time no one witnessed. The polish carries the colour without altering it.

A natural specimen. No two slices share the same banding, and the piece you receive is the piece photographed.
