Time never stands still at Waterford Crystal. The designers are always working hard to find that new angle, that innovative twist that will always keep Waterford Crystal where it belongs – right at the very forefront of contemporary crystal design. And such is the case with the Ruby Collection. Whether it be for stand alone decorative pieces or as perfect gifts for Ruby Anniversaries, the Ruby Collection represents a wonderful offering. Many of the Ruby pieces use the cased glass technique whereby two layers, one clear and one coloured are applied on over the other. The cutter then cuts the design through the upper layer to expose the lower one. The Waterford Crystal Ruby Collection. Perfect Art Glass.
