My cousin Renee has the same ring that you posted, but with emeralds in hers. If you were talking about a 20 year anniversary, I would swear you were talking about Renee.

This is the ring that she picked for herself: http://www.moissaniteco.com/65mm4mm-round-brilliant-moissanite-3stone-ring-15ct-p-11730.html

But she stuck with the emeralds on either side of the main diamond/moissanite to stay with the theme of the original ring that she loves.

She sometimes wears it as her wedding ring/e-ring, sometimes she wears it as a right hand ring.
