CoSh NYC began with a dream in the clouds. In a building high in the sky overlooking New York City's famed diamond district, the founders had a vision: cater to a clientele of young professionals desiring unique, custom-made fine jewelry.
CoSh NYC offers personal consultations to help you build your dream jewelry piece. Our talented sales professionals will walk you through every step of the process. As you pick through parcels of diamonds and gems we will make sure you are educated about the investment you are making. Whether the design comes to us in the evening overlooking the sparkling skyline, is scribbled late at night on a cocktail napkin, or thought of early in the morning on the packed subway, your custom piece will be brought to life through expert craftsmanship.
CoSh NYC is committed to providing you with the highest level of service, drawing on our many years of family experience in the diamond jewelry business. We expertly craft custom diamond engagement rings, wedding bands, earrings, necklaces and bracelets, just as our families have for the last three generations. We're proud to say that every gorgeous piece is made in New York City.
