In Antwerp, Belgium my dear Father (z"l) used this entire book to teach himself "How to Polish Diamonds" and this was in the year 1923. As he was fluent in Flemish, (the Dutch language of Holland), he could understand all of the subtle nuances with instructions being then written.
Not all diamonds have to be used in jewellery, as we know it. Many of them are not fit to be put into "pieces of wearable art". Those stones that are remaining are for "industrial consideration".
These few diagrams show the formation of the "Faceting of a Diamond" from the Table Facet to the Pavilion (which is underneath the Girdle of the stone).
To make the polishing process easier to understand, all of these facets have been given names as a reference.
This is my photo of my Dad, as "Industrial Diamonds" were literally an unknown craft in the earlier years of the diamond trade in North America. To add to this honour, he appeared on television many times.
It is because of my Father, that he suggested that I should as well enter this field. I did enter this specialized craft and after 9 years of apprenticeship, "I am who I am today".
When my (both) Parents tragically died in a motor vehicle accident I had many artefacts and books on jewellery. This book in Flemish was among those books, I gave this same book to our "Seth Rosen, of the Orchid-Ganoksin community" to keep as a gift from me.

Here are some of the books that were being used in those earlier days of jewellery manufacturing.
I find it interesting to read that the year of this publishing was 1948, and that is 76 years ago. My Father brought to North America the unusual uses of "Industrial Diamonds". Today his ideas have then turned into what is now used in building construction and aircraft along with motor vehicle maintenance regularly.
