This filigree, fire opal necklace is stunning! This natural stone necklace features a vibrant blue fire opal. It is light blue in color with flashes of vibrant blue, red and yellow. The opal itself measures 3/8 in. in length. The gorgeous blue stone is set in an intricate sterling silver filigree setting. The pendant measures just over 1 in. in length and just over .5 in. in width. With the sterling bail it hangs 1.5 in. I attached the opal pendant to an 18 in., sterling silver chain.
