I have never purchased a "Rough Cut" gem.  When it arrived, I thought it might have been damaged.  I contacted the seller and sent photos per their request.  Since it is a rough cut, there will be some obvious blemishes; however the seller was professional & offered to exchange for a different ring.  They attached photos of other comparable rings.  In the end, I decided to keep it and actually it's one of my favourite pieces. The band is great - feminine and compliments the 7ct Ruby nicely.
