I ordered these as a gift.  Purchased a similar pair for myself, recently and was pleased with quality, but this pair had problems.  Had to reorder TWICE (thank you Amazon!), but FINALLY got an acceptable pair, just in time.  I disagree with the I1-I2 rating these have.  I have purchased diamonds before and knew these were not "top quality", but the ones I received seemed far below any I1-I2 rated diamonds I've bought in the past.  It seemed to always be a problem with one earring.  Perhaps, Amazon could make sure these were better matched, as a pair.  Also, these had noticeable scratches and divots on the face or table, which is the most visible part on a solitaire diamond.  $100 is a lot of money for lesser quality diamonds.  Setting and backs were fine.  In the end, all is well; but I'm not sure I would order these again.
