Different Colored Metals and How They Go with Diamonds
This is also true for other metals used in jewelry, which is why there is a raging market for each, based on the type of ring different consumers prefer.
Non-Halo Rings: When it comes to yellow or rose gold, diamonds set in them take on some of the colors of the metal. Even ‘D’ to ‘F’ stones can look a couple of color grades lower because of this. However, there is a nice frame created for the stone, which means the diamond will be more brilliant and will have a shine.
Halo Rings: When creating a 2-carat diamond halo ring with yellow or rose gold, you normally want the stone looking larger than it is, but it rarely works out that way. White gold is a much smarter choice of metal in such instances because it can render the illusion of the stone is more of a focal point than it actually is.
For a delicate and uniform look though, yellow or rose gold are your best options. The metal color is more pronounced in the center metal when there is a halo of smaller gems around it.
