Need help on pendant.

[carguy1]

Sorry if this is in the wrong section..

I am about to purchase a custom pendant from WF, and need a bit of help as this will be a gift for my wife..

I am looking at a DBTY with .10 ACA diamonds.. The question is 14k white gold, 18k white, or Platnium. What would be better for this piece? If i go gold, should i stick to 14k?

Thanks for any help!
