The marquise-cut diamond has a very big surface area for the carat weight, so it is an excellent option if you want a big look for fewer dollars. 18-karat white gold has a very high pure gold content and requires rhodium plating for its white color. When the rhodium plating wears off, 18-karat white gold jewelry can look yellow and will need to be re-plated to regain its bright white color.
