Dear Whiteflash / A CUT ABOVE,
I am just writing to express my appreciation for the wonderful service and incredible product you provide. I was very demanding with my requests for info and yet you gladly provided all that I asked. When I received the diamond I was giddy with glee. It sparkled and flashed like it was alive. I have never seen a diamond like it. I am very pleased with your product. It looks wonderful in the setting and I know that my girlfriend will love it.
It has been a pleasure doing business with you.
P.S. feel free to use my thoughts in any customer testimony or whatever you would like.
