One of my friends asked for this today, so I made it. Anodized aluminum in blue with pink and violet.

You can have one of these too for $30. A wide variety of colors are available. (Check http://www.furaffinity.net/view/6033768/ for color possibilities. Price is for non-rubber, because the rubber rings actually make it take longer with this weave.)

Focus is a bit funny because the front of the necklace was closer to the camera and that's how lenses work.

[edit] I pulled an oops and misread what my friend wanted, so this one is now for sale! It's currently 20 inches long, note if you'd like it adjusted.
