A classic Tiffany setting in not-so-classic acrylic. This ring is available in different widths, colors and is also available in sterling silver.

There are silver or gold versions of this too - at http://www.objectfetish.com/jewelry/diamond-ring-gold-custom-order-p-2397.html (via ObjectFetish)

This ring is great! There are no diamonds in Alissia Melka-Teichroew's rings, simply a thought-provoking silhouette imitating the conventional Tiffany setting. Wearers create their own traditions, meanings, and stories.

No need to be shy about your fake diamond ring. Represent.

This will definitely satisfy my ring fetish!

This ring is a great idea. It's fun, but can also be used as a promise. I love it. I will defiantly be getting this item.

great gift for friends who may still be waiting for the diamond of their dreams... comes in many colors - great party favors!

It's killer looking!
