    I am amazed at the efforts you are putting into documenting excellent faceting history! Your series of web pages are most valuable…please keep up the great work!

    A link on your own website to the following publication, might produce the oldest documented gem design I have found to date. It is:

    Diamond Design
    A Study of the Reflection and Refraction of Light in a Diamond
    by Marcel Tolkowsky, B.Sc., A.C.G.I.
    with 37 illustrations

    E. & F. N. Spon logo
    London: E. & F. N. Spon, Ltd., 57 Haymarket, S.W. 1
    New York: Spon & Chamberlain, 120 Liberty Street

    Contained in this document, by Marcel Tolkowski, are diagrams of an SRB with very specific, although somewhat complicated, angles for faceting. I would consider this a complete, documented design, dated 1919. This entire Diamond Design Study is completely fascinating to anyone interested in seeing the details of how Marcel Tolkowski worked out the proper design for an SRB.

    Jeff, I didn’t know if Tolkowsky counted since it’s not necessarily laid out like a faceting diagram. You are correct though he does give images and angles. Speaking of diamond design, have you read American Cut: The first 100 years? I just read it and its a fun and historical read about the creation of the modern SRB and all the steps it went through before Tolkowsky and after.

    Glad you enjoyed my website. It’s a great way for me to stay organized in my research while also being able to share my findings with others. I have been in deep research mode for a bit over a year and it’s pretty incredible what’s out there to be found if you can figure out where to look.
