More shells

I'm continuing to work on lampwork glass adaptations of basic shell designs---I guess I'm becoming obsessed with this project, but I love lampwork glass bead-making and I love shells!  For this post, I've made a nautilus shell and a moon snail (which is my favorite Florida shell).  For both types, I start with a round gather made of ivory, then I pres it.  I add an extension on one side to represent the mouth.  For the nautilus, I add a twistie of ivory and dark amber on both sides in a spiral design.  I then make a twist in the center of the bead to emphasize the spiral of the nautilus.  Two examples are shown below:

The bottom bead in the picture is my version of a moon snail.  I start the same way as the nautilus, but press the extension of the shell to create the "mouth".  Then I add a twistie of ivory and sandstone (which has grey overtones) on one side of the bead only, which mimics the subtle spiral of the moon snail.  I also twist this a little off center, and add a cubic zirconium in the middle of the twist.
