Jewelry that features cannetille work is often mistaken for filigree detailing, as the two have several common features. Cannetille work is adapted from a style of fabric embroidery; featuring wire and metal sheeting crafted into delicate twists. Where filigree jewelry is a single layer that lies flat, cannetille work often takes 3 dimensional forms, such as domes, flowers, shells and scrolls. This bracelet has a unique sliding clasp, and is not marked, but acid tests as 925 silver. Its a unique piece of jewelry, and would make a wonderful gift. Bracelet measures 1/2 inch wide, and 7 inches long. It weighs 21 grams. PLEASE NOTE: I have not dipped or cleaned this piece, I prefer to leave that up the the buyer.
