What do you think is the minimum color for an emerald shaped diamond to face up white? I'm looking emeralds in the 3 carat range and I hear that you have to be really careful with color in emeralds because they tend to show color more easily than other shapes. Do you think G color is ok or will it look yellowish? There is such a price difference between DEF color diamonds and G color. I really want the diamonds to look bright and crisp white, but G color is more in my price range. Please let me know what you think!
