The Jones Diamond, also known as the Punch Jones Diamond, The Grover Jones Diamond, or The Horseshoe Diamond, was a 34.48 carat (6.896 g) alluvial diamond found in Peterstown, West Virginia by members of the Jones family. It remains the largest alluvial diamond ever discovered in North America.
The bluish-white diamond weighed 34.48 carats (6.896 g), measured NaNadj=preNaNadj=pre across and possessed 12 diamond-shaped faces.
The diamond was discovered by William P. “Punch” Jones and his father, Grover C. Jones, Sr. while pitching horseshoes in April 1928. Believed to be simply a piece of shiny quartz common to the area, the stone was kept in a wooden cigar box inside a tool shed for fourteen years throughout the Great Depression. In 1942, Punch brought the stone to Roy J. Holden, a geology professor at Virginia Polytechnic Institute (VPI) - more commonly known as Virginia Tech - in nearby Blacksburg, Virginia. Holden, shocked at Punch's discovery, authenticated the diamond and the diamond was sent to the Smithsonian Institution where it remained for many years for display and safekeeping. In February 1964, the Jones family brought the diamond back and placed it in a safe deposit box in the First Valley National Bank in Rich Creek, Virginia.
In 1984, the Joneses auctioned the diamond through Sotheby's auction house in New York to an agent representing a lawyer in an undisclosed east Asian country.
