High polish finish, this dazzling piece is perfect solo or to layer. Length is 16.5”. There is a hallmark on the stamp (picture #6: after 14K and Italy, but I cannot make it out). Kinda looks like “RL” but this piece doesn’t give RL vibes… Worn once, in great condition with strong clasp. Approx 10 grams (I have a postage, not a jewelry, scale, so not 100% certain). Please see my reviews and shop with confidence.
