These earrings have Kenyan Kazuri Ceramic Beads in black and blue, with a high gloss glaze, which gives them a beautiful shine. Kazuri is the Swahili word for 'small and beautiful'. Each bead is made by hand, polished, fired, painted, then fired again so no two beads will be identical. The earrings have a 2 1/4" drop, they have Sterling Ear Wires or Niobium Ear Wires ( if requested). The Kazuri bead style used here is called Shale. The Kazuri 'Shale' beads are approximately 5/8" x 3/8" x 3/16" thick. The ear wires are sterling or if you have metal allergies, Niobium will be provided. Niobium has outstanding qualities including being nonreactive to those with sensitive skin or metal allergies. Send a message to me with your order/payment if you require the Niobium wires. Please look at the photos with the ruler for further measurements. All jewelry wiring and findings are new and designed to be flexible and hold up to todays demands. I hope you enjoy wearing this jewelry as much as I did designing and making it!!
