Before shipping, our QC staff inspects each item at each stage of production (wax injection, casting, filing, stone setting, polishing, plating, packing, etc.). This strict attention to quality control not only assures the final product’s quality, but also helps us to discover and avoid possible problems that, if left unchecked, might result in more significant delays farther down the manufacturing line. As a consequence, we are able to meet all due dates on a continuous basis.
