Swarovski Necklace with red stone pendent

Never worn. Still has tag on it. Has been in a drawer for over 10 years. The chain does not have a clasp. Instead it has a hook that seems to hold. Has Swarovski swan emblem on the back of the pendent. Red stone is circled by crystals, I cannot get the pics any clearer with my camera. The stones have a lot of reflections.
