In the summer of 1888, a brilliant stone was found on the farm of Henry Burris, two miles north of this site. G. A. Schultz, a jeweler of Louisville, appraised it as a gem-quality diamond, octahedral in form, weighing 0.776 carat, and bought it for $20. The diamond is now on display in the Smithsonian Institution. Up to 1964, this was the only gem-type diamond found in Kentucky. No other diamond had been found in the area, although many searched. Low-grade diamonds were found in Elliott County, 130 miles northeast. Elsewhere in the United States, diamonds had been found in single locations in Michigan, New York, and Ohio; in two places each in Indiana and Tennessee; and in six places in Wisconsin. The source of these Great Lakes region diamonds was probably glacial action, although their Canadian origin had not been located. Diamonds had also been found in 10 other states.
