Powellite is a mineral in the calcium molybdate family. It typically forms translucent to transparent crystals that exhibit a yellow to amber color, with a vitreous to resinous lustre and a relatively simple anhedral to euhedral habit. The mineral is associated with hydrothermal environments and molybdenum-bearing ore zones, where calcium and molybdate ions crystallize under favorable temperatures and pressures.

About Powellite
Significant specimens have been reported from India, Chile, and Namibia, where Powellite often occurs as well-formed crystals embedded in matrix or perched on contrasting hosts. Collectors prize its cheerful color, crystalline geometry, and the way Powellite complements other molybdate and oxide minerals in a cabinet. Its occurrence alongside related minerals can aid in identification and provenance, while the mineral’s rarity in polished or prepared forms makes sharp, well-preserved crystals especially desirable for display.
