Currently one of my favourite pendants. I did a series of these in different colours and with different carvings and textures.  I like the negative space cut out in the middle because it lightens the piece.  I also softened the back rim of the pendent with a small carving tool and sponge to give it a more refined aesthetic.  What I see are more possibilities for this design, such as adding a floating bead in the negative space or linking to a couple of smaller ones for a chunky choker.
