This 20" long necklace is made of a Chinese fresh water, South Sea, Tahitian, Japan Kasumi, and Japan Akoya pearls. I LOVE making these ombre necklaces.. I personally pull different pearls and arrange them into not only gentle color flow but also play with texture and weight balance to keep the eye moving around the piece. I REALLY had fun with this one. The pearls range in size from 5.5-16mm. The clasp is 14K yellow gold "orbit" style. The luster is fantastic throughout the necklace. ID#KDN2511/KDJ4500
