prismatic crystals
Light-splitting geometric formations
Prismatic crystals are elongated crystals with parallel faces running lengthwise, shaped like geometric prisms.
The term appears in mineralogy and chemistry to describe crystals that form columnar or rod-like structures rather than flat plates or irregular masses: The quartz formed prismatic crystals in the rock cavity.
These crystals often have well-defined edges and can split light into spectral colors.
