CUTTING DIAMONDS
sawing was done on the Regent with lead strips charged with diamond dust, a process possible only where time and labor counted practically nothing. When the United States took hold of the industry, machines were soon perfected to rip a diamond in any direction at a minimum expense of both time and labor. Today there are numerous patents for sawing, convenient dops and devices for sawing and splitting the crystal, whereby time, labor, and costly mate­rial are saved.
The supply of large and splendid stones has not increased materially, but the widening market has been chiefly for small diamonds. On these the modern jeweler's trade is for the most part founded. London has become the primary market.
The depression in the diamond market began in 1927, and went on dropping until 1933 when the bottom was reached at 180,000 carats.
