While I understand adding a beard to a figure will probably make it just plain unappealing as a Hero, the idea that dwarf females are bearded is debatable by Tolkien fans (as distiguished from those who have just seen the movies). Gimli talks about this on p.360 in Appendix A of The Return of the King: "...They are in voice and appearance, and in garb if they must go on a journey, so like to the dwarf-men that the eyes and ears of other peoples cannot tell them apart." Beards are part of the appearance of all dwarf-men, and since dwarf-women are so like to them in appearance as to be nearly indistinguishable, they must have beards.
Peter Jackson has even included some bearded dwarf-women in his Hobbit film. They are hard to catch, but that's what Goolgle Image is for. Jackson was forced to account for family markets not being able to accept strange gender expressions, so he relegated bearded dwarf-women to a joke and some hard-to-notice glimpses in the destruction of Erebor. Tolkien was not so constrained, so for Tolkien fans and those influenced by his seminal works dwarf-women have beards, and dwarf-men like it. Human preferences for feminimity are set aside by those who accept his vision.
