This was a much more interesting story than mine . The 70's and man made diamonds brings back only one memory , NEVER let your girlfriend find out her ring was cubic zirconia !Back story: I can tell you exactly what happened. During this period of time manmade diamond entered the arena. The Japanese were the first to get onboard with implementation of this. It’s also when aluminum entered the scene. High in silica and magnesium. The diamond tooling allows precise tolerances never seen along with finishes that were better than anything before it. What this did was allow far better finished products that would last a very long time. It cost less to machine as tooling life was superior to anything before it. The American auto makers we’re getting their lunch handed to them. That is until they adopted the same technology along with CNC machines to make the parts. I handled the very first manmade diamond back in the mid 70’s. I made tooling using natural diamond back then so I pretty much knew what needed to be done. Later on in mid 80’s we started our own company that specialized in diamond tooling for auto manufacturers, aerospace, and general industrial uses. We were only 1 of 6 business in the country that did this work. I had more business than I knew what to do with. It was in the 90’s when the bottom dropped out. Manufacturing in the US went offshore and so did my business. Company still exists today but I sold out back in late 90’s as I saw the writing on the wall. Today polycrystalline diamond is very common and is used exclusively in all types of non ferrous machining
