Marc is excellent to work with. A true professional who honestly cares about his clients and their ultimate satisfaction. He is both meticulous and very passionate about his work. Not enough can be said about the quality of his workmanship. I would highly recommend him as he is more than adequately skilled as a jeweler and is an absolute pleasure to deal with.
