Wholesale Glass Manufacturer Couronne Co. is a wholesale manufacturer and distributor of glass and metal designs for home, event, garden and gift. Emerging from Europe in 1993, Couronne (Crown, Fr) Company, Inc. moved into the US market with vast success. We originated with a single product - Water Gems, a water based gel used with fresh cut flowers and plants. Responding to an increase in customer requests, we shifted our product line to include glassware. It is our glassware line that has since become the focus for Couronne Company and is the basis for all new product designs.
