Wulfenite – Natural, Specimen, Orange
These butterscotch-colored wulfenite gemstones show their tetragonal crystal structure. Some gems in the tetragonal crystal system form as rectangular prisms with square terminations, like these. Others can take the shape of rectangular prisms with pyramidal terminations. Some form as dipyramids, two 4-sided pyramids joined at their bases.
