It makes me angry to read these reviews and see that Luis is still scamming people. My husband bought me my ring over 12 years ago. When I initially went in I went took my mother with me to pick out a center stone. I knew that I wanted a princess cut. After being shown many stones I selected a spectacular stone that fit my budget. The clarity was remarkable and the shape of the stone was quite distinct because we had a conversation about the fact that the stone was slightly oblong but it was not a "radiant" cut. My husband went in later to design my ring with Luis and was everything was squared away. After I received my ring I knew right away that the stone was most definitely NOT the center stone that I had originally hand selected. The shape was wrong and the quality was downgraded quite significantly. In fact, there is a flaw in the side of the diamond that is visible to the naked eye. Other than that the ring was visually STUNNING. Imagine how bad I felt trying to explain this to my then fiance as he was so excited and proud. We ended up contacting Zavius and this was brought to their attention. Luis insisted that it was in fact the stone that I chose. I'm very sorry to hear that Zavius is still scamming people and getting away with it after all these years. I would NOT recommend them to anyone. They are completely dishonest. STAY AWAY!! Wish I had gone to Mincemoyer's...they have a reputation of being very honest.
