Engagement Ring - Platinum V. White Gold

Q: My boyfriend are doing some research on engagement rings. I prefer the silver colored rings, but don't really know the difference between platinum or white gold (besides price)?

A:I work for a jewelry store in Michigan, and just wanted to give you my info. Looks-wise, you cannot tell the difference between platinum & white gold. Platinum is denser (which makes it heavier), but it also acts more like taffy when the jewelers work with it, making it more forgiving to bending. This is why we prefer to use platinum heads when setting a diamond, verses white gold. White gold can be more brittle if there is a problem when they cast the heads (the whole piece that holds a diamond), and can lead to a problem called "Prong Sheering" (When the top section of the prong breaks off for no reason at all). If a prong of a platinum head gets moved or pulled away from the stone, it's possible to be able to push the prong back into place without fear of it breaking. Where as with white gold, that prong may break when they try to move it back. If the prong goes back into place, but bends again, it is likely to become weak & the entire head (not just the prong) will have to be replaced. Therefore, Platinum seems to be less problematic. As far as white gold is concerned, it will take on a slightly tarnished-look over the years since gold is naturally yellow with alloys added to make it white.
