Gorgeous Mother of Pearl Shell Skull Carvings by Gregory Raymond Halili 

 The skull shells of Gregory Raymond Halili are just that – gorgeous,
luminous, anatomically perfect human skulls carved and painted onto
small shells. He uses oil paint on raw, gold-lip and black-lip
Philippine mother-of-pearl oyster shells and the natural shape of the
mollusks echo and complement perfectly the lines of a skull.
