After going to a chain jeweler who quoted me $2500 to fix up my grandma's $1000 ring set, I took them here to get an estimate- less than $600! Now the rings look better than what they looked brand new! John knew so much about the set just by looking at it and his jeweler did an amazing job. They even had the work done in less than a week. I will be taking all my jewelry business here for years to come!
