D'Antonio & Klein is a jeweler on jeweler's row in Philadelphia, PA. My husband, through much investigation, was lucky to learn of how wonderful John and Dennis are. I cannot say enough about their creativity, knowledge, craftmanship, professionalism, and quality of work. My husband had my engagement ring custom designed and made - it is amazing to see how an idea can come to life through an artist's hands! My ring is outstanding...countless people tell me that it is the most exquisite piece of jewelry they have ever seen! We also had our wedding bands custom designed and made by D'Antonio & Klein; again, simply beautiful! Thank you John and Dennis for creating such magnificent pieces for us! I can't recommend D'Antonio & Klein enough!
