I recently order a pair of diamond earrings(under Ready to Ship category) and was genuinely pleased to see that they were delivered on third day itself from my placing the order! Their customer support personally was very helpful and can also help you make informed purchase decisions.
One of the best things I liked about this site was that they offer "Conflict Free" diamonds. While making my purchase this was a major criteria and it was sad to note that none of the major jewelry brands which overload us with advertisements don’t even make any mention of this fact. Caratlane was the only one which prominently mentioned that they deal exclusively in conflict free diamonds. I can at least now rest easy that my purchase is not fueling civil war in an African country.
I would also like to mention that jewelry was packaged most professionally in a very nice gift box and came with certificates for diamonds used.
Overall a very good experience buying from them and I highly recommend them for purchases. I’ve decided to now use them exclusively for all my diamond purchases!
Update: Would like to mention that all diamond jewelry comes with GIA certificate.
