The ceramic tiles on these one of a kind necklaces are handmade from two stoneware clay bodies combined to create the stunning marbeling effect. The ceramic tiles are glazed and fired in my home kiln to high temperature. The necklace is assembled using a 100%silk/linen blend cord and an african metal engraved wood bead. The cord is adjustable to your desired length. The tile measures 2" 1/2 across and about 4" down to tassel.
