Gorgeous Juliana (D and E) stretch cobra style collar necklace done in silver tone. The centerpiece is a gorgeous set of vitrail light (the medium is often called watermelon along with clear and AB rhinestones. The matching earrings to this necklace are also available on RubyLane with a different seller (and marked KJL) if you are interested. The necklace measures 17 inches long and 5/8 inches wide. The rhinestone centerpiece measures 1 3/4 by 1 1/2 inches. Nice shape.
This necklace is a variation on the necklaces found on page 45 of my book Juliana Jewelry - The Last Generation.
