I painted each glass focal in these necklaces and each is unique. The paining on back gives the necklaces and earrings a sparkle (which is difficult to capture on camera). There are a few necklace and earring sets available. On average, each necklace is 16 inches long with a 3-6 inch extender.
The black and purple focal measure 2 inches and all the other colors measure 1 6/8 inches.
