Controversial opinion - Skip the white prongs!
Hi all! I see a lot of posts here with people looking for yellow gold settings with white gold or platinum prongs. My recommendation? Skip the white prongs. Diamonds are so highly refractive that the white prong won't significantly affect the color anyway, and having the ring cast from one piece of solid metal makes it not only more durable, but more cohesive and elegant looking (IMHO).
So, if you're debating putting white prongs on a yellow gold ring, I'd reconsider. Just go with all yellow for a clean, timeless look.
