Crystal offers the larget selection of choice woods. Wood grain patterns display the inherent, natural beauty of wood. Differences in color and wood grain are directly related to the life of the tree and variations in forest growing conditions. The color of the wood will always change as it is exposed to light, both natural and artificial, over time. Some species, like cherry, will change dramatically and quickly, others will change subtly and slowly. This will occur even if the wood has a colored stain over its natural beauty.
