To figure out what diamond you need for a rose gold ring you’ll first need to decide on how “rosy” the gold is going to be.
The pinkish or reddish color of rose gold depends on how much copper is in the alloy. 18k and 14k rose gold are the two popular rose gold alloys used in fine jewelry, with 18k gold being more expensive and softer than 14k rose gold.
Now, with that out of the way, what color grades should a rose gold ring’s diamond be?

On one hand, rose gold doesn’t really restrict your choice of diamonds by much – if you have the budget for a perfectly colorless diamond, that would make for a striking contrast between a cool toned diamond and a rose-toned metal.
Jedoch, the factor to consider is that unless you have a halo of white diamonds around the stone, you can expect the rose color of the metal to affect the diamond’s color too, giving it a tinge of warmth. Also, instead of shelling out cash for a completely colorless stone you can go for a diamond that’s slightly lower on the diamond grading scale.
