Celtic triquetra knot necklace is handcrafted from silver-filled wire* and 3 gorgeous cat's eye glass stones in your CHOICE of color (see last photo for options). Model pieces shown in "Kelly" and "Seafoam." Choker style necklace has a sterling silver spring ring clasp and adjustable cable chain for a length of 16-18 inches. Please see third photo for measurements. Necklace will ship gift-boxed, perfectly ready to treat yourself or a special someone! Please note that due to the creation process for cat's eye glass, the red color (cherry) does not have the cat's eye (chatoyancy) effect. *Sterling silver-filled wire consists of a thick layer of sterling (30x thicker than any silver plated wire) bonded to a white brass core. The advantage of this is that it looks, feels, and lasts similarly to pure sterling, for a fraction of the cost! It meets the same legal requirement of "gold filled" as it is no less than 1/10 sterling silver.
