Pyroclastic is a geological term for fragmented material formed by an explosive volcanic eruption; “silicified” describes later silica enrichment or replacement. The stone's contrasting fields make it an appealing display specimen or a piece to assess for lapidary work. The clear stand is shown for photography and is not included.

Working stone: If cutting or polishing, use appropriate wet methods and dust controls, and avoid breathing stone dust. Individual mineral composition and cutting suitability have not been laboratory tested.
