First established in 1983, J.G.DURAND is the prestige brand of ARC INTERNATIONAL . The company's midrange pricing policy enables it to offer crystal stem glasses at between 10 and 20 euros. A selective distribution policy means that J.G.DURAND products are available only through specialist retailers and department stores. You can clean your JG DURAND crystal glasses in a dishwasher if you take certain precautions - Depending on your dishwasher, use the "fragile" or "special crystal" programmed at moderate temperature. - Space out the glasses so that they will not knock against each other. - Place them fully upright in the compartment "reserved" for this and ensure that they are quite stable.
