I went to Roman Malakov based on a friend's recommendation to get an engagement ring. It turned out another friend had been there too and was also very pleased.
I dealt with Boris throughout and the first thing that struck me was that he was very friendly, but no-nonsense. There was an understated sense of quality that is lacking at other places on the street who have salespeople on the street trying to pull you inside.
Boris was thorough in explaining the way that the industry measures quality, as well as guiding me through the different levels of clarity and colour. I wanted to be sure of my ring so I had a friend of my fiancee take her there to look at the rings "for fun". Boris was smooth and didn't give the game away and got the size of her ring.
The price was great, and they were very flexible on timing to accommodate my needs to get the proposal done on the weekend I was aiming for. Everything went great, though the ring needed a minor adjustment, which they took care of also.
I would highly recommend this store, and not just for engagement rings. The trust I built during this process would take me back again and again. Thanks!!
