I got this ring to wear when traveling and when I want "white gold" instead of the yellow gold setting I have.  It looks so real no one would know it's not a diamond.  The metal is the color of white gold rather than the bright color of silver, so I can wear it between two white gold bands I have, and it's a perfect match.  I am very pleased with this ring.  It's just what I was looking for!

Update after 6 weeks: I still like this ring but the stone looks dull after wearing it continuously. If its just cleaned it looks OK, but otherwise it's not as brilliant as when new.  That being said, most people don't keep their rings really clean and sparkly, so it looks like it just needs to be cleaned.
