Genuine Emerald, Emerald Gold Scallop Necklace May birthstone Camp Sundance Gem Bliss. Emerald, a precious gem, is the May birthstone. Emerald, a Beryl, is the most expensive green gemstone. Chromium is primarily responsible for the green hue in these gems. For your consideration, five genuine faceted Emerald briolettes in this 14k Gold filled Scallop necklace, 19.5 inches long. Green Emerald Heart Briolettes 7-5mm, with minor pitting, which is preferred as these imperfections show the stones have not been treated. They are faceted opaque dark green, a forest or hunter green with some slight black veining. I have added faceted Labradorites to bring out the teal blue quality of these Emeralds which have been hand wire wrapped using fine Gold filled wire to secure them to the Scalloped part of the necklace. Necklace is trimmed with green Onyx then finished with a lobster clasp from Camp Sundance Gem Bliss. Ask about the matching earrings.
