Before moving forward with this discussion, it is important to emphasize that both yellow and white gold have exactly the same hardness. As explained previously, the hardness of gold depends on what karat the gold is, since 14k gold being harder than 18k gold. When you are deciding between yellow or white gold for your wedding band you should also think about the color of the gems (if any) that will be set in the ring. Some gemstones, such as rubies, topaz, emeralds, and citrine etc look fine in either white or yellow gold band rings. However, for the darker gemstones such as dark blue sapphires, white gold tends to enhance the color contrast between the white of the gold and the darkness of the gemstone. This will causes the dark sapphire to look even darker and sometimes black in many cases. If you are not sure about what stone looks good with your choice of gold color, you might want to ask a friend for their advice.
