This very feminine 15k necklace has a long history beginning with the central element. The central motif is a carved emerald surrounded by flat cut diamonds set in silver. This section is circa 1800. The central stone is an emerald carved scarab. It was originally a bead used on a necklace or ornament, then considered valuable enough to be used as the focal point of this drop circa 1800. The reverse of the pendant is finely engraved in gold. There are four pink topaz faceted lozenge shape stones that are bezel set and interspersed with pearls which enhances this lovely play of color. This likely followed the fashions of the 1890's and the Art Nouveau movement. The necklace measures 15 5/8 inches long. The central section is 1 3/8 inches x 7/8 across. This is a strikingly beautiful,elegant necklace.
