Consider the diamond’s color grade
The diamond’s color grade refers to the hue of the diamond. The GIA grades diamond color on a scale from D (colorless) to Z (yellow or brown). Consider choosing a diamond with a color grade of G or higher for the best value.
Consider the diamond’s carat weight in relation to finger size
The carat weight of the diamond should be considered in relation to the size of the finger it will be worn on. A smaller carat weight may look larger on a smaller finger, while a larger carat weight may look smaller on a larger finger. Consider choosing a carat weight that looks proportional to your partner’s finger size.
