18in. silver chain with additional 2in. extension for extra length if needed. This necklace is made of turquoise Heishe or Heishi beads with silver accent beads and Dyed Imperial Agate pendant with reddish brown veining. Instead of making this necklace on beading string as most do, I have made the necklace with silver chain to increase its strength. This is the perfect necklace to wear with a summer outfit or to the beach while flaunting that oh so cute bathing suite. NOTE: Only the lavender necklace is for sale. Other images are only suggestions on how adding additional layers makes the necklace even more special. Thank you for visiting JewelrybykarenM and please share to you family and friends.
