Scheelite itself belongs to the scheelite mineral group, which also includes powellite, stolzite, and wulfenite, and forms a series as the W end-member with powellite, the molybdenum (Mo) end-member. All these minerals are rarely seen as faceted gems, but scheelites are probably the most commonly cut of the group.
