Astrophylite is frequently visually confused with nuumite, arfvedsonite and copperite, although it can easily be distinguished by it’s elongated golden blades, which much resemble a yucca plant or skinny palm frond. Copperite and nuumite often have a more abundant show of quartz, and squarish flecks of copper crystal and mica, whereas arfvedsonite exhibits a deep blue bladed labradorite type of flash, and the previous minerals are all exclusive to the Greenland area. Although astrophylite is found in more locations, it is not found in abundance, and so remains rather rare.
