There are "Diamonds being used in fine quality jewellery" and then there are "Diamonds being used in industry". These are still diamonds, but these uncut and unpolished stones even have another name to them. They are named "Boarts".
What do these stones look like? I looked through a jewellery site and at Google, until I found a tight group of these stones to show you.
In my previous essay, I wrote about these diamonds extensively, but then I had to carefully separate these topics on "Diamond Polishing". separate these topics on "Industrial Diamond".
================ "MY HISTORY LESSON, just for you!" =======
In those earlier years while living in England during the "World War 2", we had very difficult times. Just living day by day, or by the hour, was a trial for the strongest. 'We' had to survive by creating methods to make an income. Those who created the 'best' idea, won their own war.
My Dear Father got married in Manchester, England and he brought with him an interesting feature through his knowledge of Diamonds. He was initially a "Diamond Polisher" in Antwerp, Belgium, but through 'some measures of fate', his life turned around by using his Diamonds.
His 'creativity' started in seeing how these could be used and "the ball started to roll, and it continued further at a fast pace". My Parents came to live in London where there he set up shop making high-end jewellery, as you can see that Diamonds played a great role in his life.
During those horrific years the war played a terrible time for everyone. But somehow my Dad managed to survive, but the problems continued and bombing by the Germans made everything more troublesome. It was a 'survival of the fittest", but my Dad did survive...greatly!
In those years circa 1942-1945, (I was born in May, 1943) were 'unbelievable to say the least'. We were told that there must not be any lights shining in our homes for the Germans to direct their bombs attack our homes, or businesses. Our apartment building were in direct line of the rocket Fueled, "Buzz Bombs". When those rockets ran out of fuel, they would just stop working . . . . they would just quickly crash.
When people heard those "Buzz-Bombs" as they made a buzzing sound flying overhead, (as they were known) we were constantly running for our lives. Sleeping was a difficult as many times through "Blitzkrieg' many people had to literally sleep in the "Tube' stations otherwise known as Subway stations. People lived that way for days, or even weeks on end, and you call this living?
My Dad one day told my Mom "Sarah, it's not safe for us anymore, we're getting out of here...as soon as possible!" My Dad had look for a safer country? Was it going to be America, or maybe Canada. He had his Mother living in New Jersey, USA. But after researching other countries; Canada became his final choice, with him came his fantastic knowledge of Industrial Diamonds. While living in England, he came known as a relative great supplier of Natural Diamonds. His business so well needed in England, he made and sold "Diamond Tools" for the English (Wartime) Government.
They needed him greatly for his knowledge of "Industrial Diamond Dresser Tools" that were made to make thousands of bombs, aircraft companies and other wartime machinery needed his Diamonds that were used in cleaning grinding wheels. Now these cleaning wheels had diamond dust impregnated in them. These were never heard of then, not until my Dad told them about this novel addition to each grinding & cutting wheel.
Only his Industrial Diamonds kept their grinding wheels clean from getting clogged up with steel. These were called "Diamond Dresser Tools". There wasn't anything else that would keep them clean 100% of the time. He thought of Australia and then America, but eventually he settled upon Canada in 1947. We eventually left England to go to Toronto.
Then in 1953, as my Dad was coming home for dinner one day, my Mom greeted my Dad at the door. "Maurice, you're going to be famous, the "National Film Board of Canada" telephoned you and they want to make a movie on your Industrial Diamond business".
I still remember this even today, my Dad thought my Mom was joking (to use a better word) She said "Maurice, I'm not joking".
The story was that no one knew anything about these non-jewellery diamonds. He was a forerunner of this new industry, in those years, diamonds were only used in making jewellery. The Industrial Diamond industry was about to change, "with the many thanks to my Dear Dad". These unusual looking, natural unpolished diamonds were still in their infancy. Machinists were still trying to see what they could do with these stones. In those earlier days, Industrial Diamonds were then still a novelty.
Eventually, these Industrial Diamonds were starting to become an interesting & useful tool for everyone. With this new diamond tool, my Dad began to travel across Canada showing machine operators what they could do with these new diamond tools.
His major client was "Massey-Ferguson" and "Hayes-Dana Steel, of Canada", plus some American metal manufacturers began to hear and assist my Dad to produce their metal cleaning tools, now with diamonds in them. (Americans were always very helpful).
I knew these names personally, as I sold some of those tools to them after my Dad & Mom were killed in a car-truck accident in 1968.
What did these "Diamond Dresser Tools" look like. These few "Diamond Dresser Tools" left with me were enough to write these informative tutorial-essays!
This display of Diamond Tools appeared with him in his film.
This is my Father on the right-side of this photo, holding the forerunner of a machine that makes girdles on EACH Diamond. From this, every square crystal shaped diamond, is then made...round.
From this 'round shaped-diamond', it's then given to a Diamond Polisher who will make multiple facets on every stone. "Only a Diamond can do any form of diamond shaping" as we can see this "process being pictorially demonstrated", that's shown further down in this essay.
This photograph was of him (on the right) in Antwerp, Belgium when all of "This History" was just starting to take place in 1932 A.D.
As shown in this tutorial-essay, I'm showing you now how the many uses of these Industrial Diamonds are being used. From this Faceting process, the next process is to start the all important 'Diamond Polishing". Every step is important. As I always state...."There are no short-cuts in any Diamond Setting", even now Diamond Polishing.
These steps are: 1) Mining of the stone, 2) Girdle making, finally, all of the very important 3)Facet making of each and every stone...!!!
Where could any short-cuts occur? It's because, there aren't going to be any!
BTW, You can just barely see the "rounded edge" of this Girdle. This is the 'beginning' of any Girdle on any diamond.
In this photo nicely shows how a fine grouping of stones that evenly address a worn down a well used grinding wheel. This portrays how some of Dad's "Dresser Tools" work, instead of using one single stone, this machinist uses a soldered collection of small diamonds together on a steel hollow square tube. Being hollow, prevents a substantial heat build up. Interesting idea?
In this portable travelling scale you can see the actual weights used by the operator.
