    Transition to Diamond

    The company begins to use its metal reclaimation technology to reclaim diamond from segmented jaw blades used locally in the manufacture of tombstones. This was initially sold to New York City diamond brokers, who used it as the raw material for diamond powders produced via traditional mortar-and-pestle techniques.

    Micron Grading System

    The company develops the first simple grading system for diamond powders. Though crude by today's standards, this manual grading process utilized microscopes to classify diamond powder sizes.

    Material Optimization

    Beginning in the early 1970s, Kay developed technologies to control the shape of diamond particles to maximize their lifespan and cutting efficiency.

    Innovations in Diamond Grading

    Over the rest of the decade, Kay developed a number of breakthroughs that dramatically increased the quality, consistency, and usability of our diamond products. These innovations include:

    • Custom mill shaping to provide highly uniform and durable blocky monocrystalline diamond particles with a high number of cutting edges per particle.
    • A unique elutriation system that allows us to properly wet superfine diamond powders, holding them in a uniformly dispersed suspension.
    • The first-ever use of pressure-sensative adhesive to adhere diamond particles for grinding and polishing. This was followed by the first-ever use of multiple pressure-sensative adhesives for specific applications and industries.

    Laboratory Expansion

    The company built a custom 2800m2 laboratory facility for both production and research and development activities. This specialized environment allowed the company to produce over 22 tonnes of micron powders annually.
