Using the finest examples of Swiss blue topaz from Russia, this charming butterfly necklace is beautifully eye-catching. Each stone is near internally flawless and cut to perfection to ensure an electrifying finish is achieved. We liked this piece so much that we crafted a pair of matching earrings to finish off the set. Four blue topaz, grade AAA, total 0.6 ct. Marquise cut. Pendant suspended from white gold double link rope chain with spring clasp, length options from 14\" to 24\". Available chain thickness 0.68 mm (pictured) and 1.15 mm.
