Product Overview
Pegmatite is an igneous rock that contains two vastly different crystal sizes. This combination of both phaneritic and aphanitic crystals indicates this rock formed at two vastly different cooling rates. Pegmatite is a classic rock for teaching igneous petrology, and is also useful in volcanology classes.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
