After having a problem with inaccurate sizing of my husband's wedding band at another store on jewelers row in chicago, I turned to Gregg Helfer Ltd. desperately for help. They offered great customer service… hard to come by these days. They created the perfect ring for me within one week and plenty of time to spare before the wedding.
