Variations on Silver Clay Keyhole Clasps

As promised, I have a couple of iterations on the keyhole clasp I made for Tonya Davidoson's Whole Lotta Whimsy Master Muse collection.


This page from my sketchbook shows my sketch for the original (third version) clasp, then my brainstorming on what elements I could change for interesting variations.
The clasp in the tutorial has a triangular hollow clasp formed over a polymer clay mold and a round insert embellished with a bezel set cabochon. The variations are for different shapes and stone settings.
