"...It is rare to find people in the diamond business who take so much joy from simply doing the best job for their customer that anyone could ever do.

At some point in the process I was struck by the extraordinary drive shown by you both to not only meet your own high standards but to meet mine as well. The loose diamond is exquisite, and not simply because it is a GIA graded D Flawless stone...
