Choosing the Color of your Engagement Ring
Your basic choice is yellow gold or white gold. Yellow gold is the traditional choice and this should be 18K. If you choose white then platinum is best, or if your budget is tight go for white gold. It is common the settings on yellow gold rings to be made in Platinum (or white gold).
Because platinum is very white, it shows off colorless diamonds beautifully. But diamonds of ‘I,J and K’ color or lower should be set in yellow gold, because the contrast with a white setting will make your diamond look a little yellowish.
