Dear Sir,
I_'was informed that you produce and sell equipment for artificial diamonds.
We, the Diamond Industrial laboratory here of the Technion - Israel Institution of Technology are interested to get detailed information about this process. What type of syntetic diamonds can be produced and what is the quantity which one unit can give per day?
Can the compacts be done on £he same press? What is the capacity of the proposed press?
A friend of Dr. Samuel Greenfild from New York who came to Israel gave me some samples of black platlets which are soft. Is it compressed diamond powder? One piece was thicker and it was written apon it "Diamond Run" . What does this mean?
Please send me possible information as well as price of the unit?
I have asked some of my friends in the U.S.A. to contact you, for more detailed information.
My laboratory is devoted to research in the field of diamonds and is sponsored by the Israely Diamond Instituties.
Thank you in advance for a prompt reply.
Sincerely Yours Prpf. Y. Yarnitsky
Head of Diamond Research lab.
