Who made them, why did they make them and how did they make them? We certainly can't duplicate them with modern technology, presuming that we wanted to. They have been found in various locations throughout the world. Microscopic examination of the "legitimate" crystal skulls shows no tool marks.
Scientists are finding it difficult to explain how a primitive culture (because the skulls are known to be at least several hundred years old and possibly some several thosusand) could have carved crystal into such precise shapes and against the natural axis of the crystal.
Crystal is a mineral characterized by perfect molecular symmetry . When a "jeweler" cuts crystal, and attempts to carve against this axis, the crystal shatters.
Even with todays elaborate laser equipment, it would be very difficult to create such crystal sculptures.
