I did research my loose diamond purchase according to cut, clarity, and Color with very tight specifications. After finding the GIA graded diamond that fit my specific required specifications. I chose Ritani due to the fact that they sold the diamond to me $160.00 less than anybody listing the same diamond from the same cutter. I verified the GIA inscribed number which matched. They delivered on time as promised and did not pull that money until the item was shipped. They were also nice enough to have included a free appraisal. They did a wonderful transaction for me personally.
