Deb Luvs this necklace because it is unexpected in it's combination of elements and yet they seem to be a match made in the sky! The sky blue beads are Howlite in 2 shapes...the large rounds are 12mm and small discs . You will also see amazing "peanut" or "bone" shaped beads in silver tone metal with rhinestones embedded in the ends (these add the sparkle to the sky). There are tiny silver glass seed beads throughout and the necklace is finished with a strong magnetic clasp in silver tone with diamond cuts to create additional sparkle! I really LUV this one. The necklace is 18 inches long. LUV this one and get some Sky Sparkle in your life
