Although most crystals don't show it clearly, the bottom pyramidal faces slant at a different angle from the top pyramidal faces. This demonstrates the symmetry of just 4. This symmetrical oddity only adds to wulfenite's interest among serious collectors. Color is red, orange, yellow, silver and white. Luster is vitreous.
Crystals are transparent to translucent.
At times the pyramids become prominant and psuedo-dipyramidal crystal habits are seen, sometimes because of twinning. Prismatic faces are also seen and can make psuedo-cubic crystals. Also encrusting and cavernous aggregates due to intergrowth of crystal plates. Cleavage is perfect in one direction. Fracture is conchoidal.
