Creating Fine Jewelry in New York City Since 1980

About Us

When buying fine jewelry, it pays to deal directly with a reputable U.S. jewelery manufacturer - not a jewelry marketing website.  
Mondi has been a manufacturer of fine jewelry for more than 40 years, built on an impeccable reputation as an expert and trustworthy wholesaler and retailer of diamond and gemstone jewelry.
    Our location in New York City's famed Diamond District allows us to provide our customers with the highest quality diamond and gemstone jewelry at the absolute best possible prices.
      All our pieces are made in New York City by our expert craftsmen using the finest materials. 
      Unlike many big box and mass market sites, we never cut corners; we use only the finest quality conflict-free diamonds, hand-picked gemstones and solid 14K (or higher) gold in all our jewelry.
        Being family owned and operated for three and a half decades, we are dedicated to providing every customer with unmatched personalized service and prompt attention. See Reviews 
          We offer a 30-day return policy and a one year warranty on all items we make. 
            If you don't see exactly what you are looking for on our site, ask if we can custom make it for you.
              GIA-certified conflict-free diamonds, engagement rings and wedding bands are our specialty. So feel free to ask us for a quote! 
                We welcome any questions or inquiries you may have and are eager to make you our customer, so please do not hesitate to call us at 212-764-4005 or email us at

                   Expert workmanship, rock bottom prices, and highly personalized service has brought our customers back for more than 35 years
