Here's mine:
I bought it from Dana Dow Jewellers in South Centre. Model number: WB-7108-M10 (although I have seen it as WB-7108SP)

It was originally made of 10k gold. I quickly found out that I have a nickel allergy (white gold is made by dying the yellow gold with nickel) and had to have it either replaced or fixed.
Dana Dow contacted CrownRing and they offered to re-make my ring out of
palladium. I paid a bit extra, but at least I didn't have to replace the ring. We had already had all our wedding photos using the original white gold ring.
So if I can offer any advice it's this: make sure you don't have a nickel allergy, if you're buying a white gold ring.
Seems like a lot of the tungsten and titanium rings are pretty cool now.
