Diamond is a contemporary cut crystal barware collection that marks the introduction of new materials into the RB collection and the development of a complete tabletop offering. Diamond brings a clean-cut look and feel to lead crystal barware. This has been achieved by designing simple forms which are mouth blown and then hand cut with a tight diamond pattern to the lower third and bottom of each piece. As light passes through the crystal it is brought to life by refractions which create a myriad of colours and glistening sparkles. Wash your crystal by hand with warm soapy water and a soft sponge. Scouring pads or abrasive washing agents should not be used. Do not put your crystal in the dishwasher as the detergents can permanently dull or scratch the surface. Dry your crystal immediately after washing using a lint-free cloth. Do not put your crystal in a microwave or conventional oven. Do not store your crystal glasses upside-down, the lip of the glass is delicate and may be damaged under the weight of the glass. Do not store food or beverage in your crystal, only use your products for serving. Prior to using decanters for the first time fill them with 50/50 solution of vinegar and water and let stand for 24 hours. Rinse thoroughly and dry.
