Importing Industrial Diamonds, sorting them for quality and shape, allocating them for specific uses, and fabricating them into tools has been our function to industry since 1886, over 100 years. Our research and engineering facilities have been continuously concentrated on the phases of this highly specialized business, from the intricacies of the rough diamonds and their precise applications, to the formulation of our own special alloys and setting materials which are so vital to producing fine quality tools and wheels.
