Working with his crew, Mr. Morse was constantly building, rebuilding and perfecting his diamond cutting machinery and also became an expert cutter and polisher in his own right. In or around 1875, Mr. Morse invented a sort of double lathe, which enabled two diamonds to cut each other by attrition produced by rapidly revolving machinery. He also invented the "Morse" gauge, an instrument for regulating all the angles to be cut on a stone. After much study, Mr. Morse discovered that the proper proportion for a diamond's profile is one-third above the girdle and two-thirds below it . The Morse-cut diamonds, with their round outline girdles and perfect profile proportions, were called "Boston Cuts". Believing in the equality of men and women, he trained the latter to cut stones, the first to do so.
