Finding the right diamond(s) for your ring is vital to its overall appearance. Subtle diamond qualities, that may not be evident at first, play a role in a ring’s beauty. For example, whiter diamonds are needed for white metal rings, while warmer diamonds are better used in yellow metal rings. Talking with your gemologist will give you the opportunity to make an informed decision about the best quality diamonds to use for your custom engagement ring. Typically, you’ll have several different diamonds to choose from, each with different prices and qualities.
