Thank you for your reply i really appreciate the insight. I got a hold of another Diamond which was certified by GIA as a J color. I put them side by side and you are correct, much higher. I came to the conclusion it is most likely a K color. Still, the Diamond is more than desirable. An emerald step cut is also what I ended with after much comparing. Your advise helped determine a lot of the color analysis though so thank you. It is always nice to get an opinion from outside eyes.
