White, translucent, and dark blue clay is marbled together with silver leaf then cut into a 1.75" diameter circular ring and a 1.25" x 0.75" rhombus.  Both are sealed in resin then connected with an 8mm round cobalt blue crystal with a thick silver-plated edge hanging inside the ring.  The earrings use silver-plated fishhook earwires and are 3" long.  
 
All metal used is nickel-free and either sterling silver, silver or gold-plated, or stainless steel unless noted otherwise. Every item is handcrafted and custom-made, nothing mass-produced.
