While colorless stones are rare and cost more, near-colorless stones will look essentially the same to the eye when set in jewelry. Choosing a G-H-I-J color instead of one in the D-E-F range will enable you to get a larger diamond for the money. If the diamond is to be set in white gold or platinum, select a color, which is a little higher on the scale, than you would if setting it in yellow gold. Yellow gold disguises color; white gold and platinum can reveal it.

*For engagement purposes, I recommend G-H-I color
