    Evan Smith, if you can see this, check out RJK Explorations. The Nipissing Diamond was found between 1903-1905 and Tiffany and Co cut and sold the diamond in 1906. A paper announced Tiffany's sent a team of explorers west of Lake Temiskaming, Ontario to search for more, but nothing else was announced in papers after November, 1906. RJK found two diamondiferous locations west of Lake Temiskaming this year, and they're drilling again now. RJK has some clear KIM trains, and it would be really interesting for you to see what types of indicators they have, to see if in fact they contain the deep indicators correlated to large, deep diamonds. The area is located above a subduction zone where two continental plates collided, on a craton, and there are major cross faults too. Could be great additional information for your studies.

    Evan Smith, e se acaso uma pedra que tem muitas características : risca Corindo e não é riscada por corindo/ e apesar de transparente não se consegue ler através dela.Alem que possui Trigons e ou veios triangulares.
    Só que esta pedra afundou no teste com o Diiodometano.E também não passou no teste com o Identificador de Diamante( pequeno e chines).
    Por se tratar de uma pedra com tamanho grande.Há chance de ser um Diamante?
    Posso tentar tirar um pedacinho dela e enviar p GIA?

    I have some sources for the great sample for your scientific research of diamonds.

    Os diamantes gigantes ou grandes diamantes podem apresentar uma Densidade menor que 3,32?( Diiodometano) ?
