Nick,

    I think you are confusing sintered with plated. Not the same thing
    at all. Sintered is a much better quality and longer lasting
    product. Not cheap, but usually worth it. 

    I have used plated and sintered diamond products for almost 35 years.
    As a faceter, a well-manufactured, top of the line plated disc will
    last a few months, costs maybe $120. A sintered disc will last many,
    many years, but costs almost $400. Obviously, the sintered is cheaper
    in the long run, but, in my experience, most jewelers and bench
    people are "cheap".....so they hurt themselves. And, many workers use
    the small tools with no lubricant or with water. They need to be used
    with a proper oil to maintain life, but, of course, many
    manufacturers will say water is fine. That's nonsense and
    self-serving. A good water-soluble oil is proper with ALL diamond
    tools. All.
