The color of these beautiful crystals is simply amazing! Makes me long for the Carribean :) The 8x10mm Chinese Crystal beads are perfectly clear with a faceted surface to really reflect the light. This pair is wrapped in gold-plated 20g wire. The earrings are just under 1/2" in diameter. They come with plastic & metal large earrings backs to help hold the earrings onto your ears more securely. These earrings are bright and beautiful - perfect for Spring and Summer. Aquamarine is the birthstone for March (and sometimes December), and this blue pair works perfectly as a more affordable substitute. Available in most other birthstone options - just ask! These earrings are also available in silver-plated, antiqued brass, black-dyed copper, rose gold-plated, or copper.
