I was initially skeptical purchasing a diamond ring from amazon but am happy to report that the ring, as well as the experience has been great. Initially shipping was scheduled for many weeks out, but I needed the ring before the scheduled date. I contacted the seller and they expedited shipping without additional charge. Once received I was pleasantly surprised to find a ring with dainty, yet substantial diamonds that were very sparkly & clear. The ring also came with a guarantee and certificate of authentication. Very happy - will purchase other pieces of jewelry again.
