Radiola

Hang seven necklaces apart on radial spines

A necklace hanger drawn from a radiolarian, the glass-skeleton plankton that bristles with radial spines. Seven knob-tipped spines fan over the top half, each holding one chain apart from the next; the boss on the back stands the disc 14 mm off the wall so chains drape behind the spines.
