I read some sites recommended diamond color H-G in colorless range for white setting, and that I-J colors may look a little yellow in platinum or white gold setting, or they are off colors. Some site cited that I-J color is still in colorless range for white setting.What do you recommend? I looked at I color diamond at Zales and they look colorless to me. I put it next to my G color diamond, and the other looks more transparent. I hardly see J color diamond in platinum setting though.
