Mixed quality, good customer service
Quick shipping, good quality packaging. The stone I received was chipped but otherwise very good quality. I contacted customer support and they were very helpful and arranged for a replacement which also arrived very quickly. The replacement stone did not have any chips, however the quality of the crystal itself was lower than the original. I.e. the original was mostly deep purple and dense, the replacement was very light purple/brown/transparent. I certainly can't complain about the final result and the customer service was great, however I know I would have returned the second stone if that was the one I had received in the first place.
