shell there are several layers that have different color pigments. Right beneath the dark green is a thin layer of gray. Beneath that a teal color that sometimes is more turquoise than teal and as beautiful as a gem. The last layer in every emu eggshell is snow white and paper thin. To expose this through carving is very difficult. But I used the different layers to carve relief work into the shells. Since I have been asked to show more of my work, here are more photos.
