I took my engagement ring in to have the diamond tightened. I was told that they had to rebuild the prongs around it. They quoted me around $ 100 to rebuild EIGHT prongs. When I went to pick it up they had only rebuilt FOUR because that was all that it needed. Even though they only did half the work they STILL charged me over $ 100! Pretty sure they are just rip off artists. DONOT go to this jeweller.
