FOR SALE, Amazing! This necklace is absolutely gorgeous! This is a very rare N3 Welo Ethiopian black opal of 4.71ct set in an 18kt solid gold bezel with a solid gold back; the back is not cut out! This beautiful stone has very bright colors with plenty of golden, orange, red with green and some of the rare blue color play! It is cut in freeform cabochon, almost tear drop. The back of the stone is common dark opal, while the top is precious crystal; TOP quality! This greatly enhances the colors saturation! It is also a good night stone; very bright indoors under artificial light! This is NOT a doublet!! It is solid opal. The gemstone measures 21.3mm x 10.8mm x 5.7mm, and a year ago, had a value of $1,900.00, unset. I have had it set in the 18kt gold and placed it on this beautiful necklace of Swarovski light green and clear crystal beads and seafoam colored pearls. It closes with a gold plated fish hook clasp. The pendant measures 1 1/4" long x 1/2" wide, and the necklace measures about 20" long. This necklace could easily be priced OVER $3000.00!
