Good things come in small packages - especially those little marbleized blue shopping bags with "Castiglione's" stamped in gold. A recipient of such a bag knows there will be something good inside and the name on the bag is as important to the owners and staff of Castiglione's Jewelers Inc., as it is to the customer. Certified Gemologist Appraiser Lou Castiglione Jr. is one of only twelve people in New York to hold that title. Certified Sales Associates Andy Castiglione is also very knowledgeable about the field, continuing his adult education through training and seminars. Castiglione Jewelers Excellence & Quality.
