“I was like ‘Oh, my god, I found a diamond,’ ” said Jillian Kelly.
Kelly, 49, left her Silicon Valley career to take up mining 10 years ago and wrote ‘The Miracle Miner: My Life as a Female Gold Miner.” The uncut semi-clear pebble-sized stone is about width of a dainty pinky finger.
While relatively rare, “as many as 600” diamonds have been found in California since the 1849 discovery of gold triggered the California Gold Rush, according o the California Geological Survey. Few are of gemstone quality.
“It does happen around here,” said Heather Willis, manager of Pioneer Mining in Auburn. “You can find them. Most of them around here are not jewelry quality.”
Because found diamonds don’t closely resemble the shiny rock on wedding bands, many could be tossed by casual miners, said Don Drysdale, a spokesman for the California Department of Conservation.
“Diamonds found in nature aren’t necessarily recognizable as diamonds to most folks, so who knows how many have been tossed aside by recreational gold-seekers over the years?” Drysdale said.
Historically, most diamonds found in California are small. The 1983 printing of “Minerals of California” put the largest diamonds found in the Golden State at 2 carats, but there have been some massive diamonds found in Trinity County. During the 1980s, a retired geologist and miner found three diamonds of record-breaking size, the largest a whopping 33 carats. It was however, industrial grade quality and greenish-brown in color.

The Only Diamond Mine In the World Where You Can Be the Miner
Kelly and her mining partner have been working their federally approved mine for about seven years. Several miles outside of Forest Hill, the site once had been mined with hydraulic dredging, before the practice was made illegal in 1884 because of environment damage. Since then, the site has been picked over by various mining outfits.
Here an ancient river flowed south to north millions of years ago, before tectonic forces created the Sierra Nevada range.
Their mining process involved digging out and processing the cement-like block of rocks at the bottom of this ancient river. Power tools help her free the rocks, which are then put in a cement mixer for several hours to break the material into small bits. Those bits travel down a sluice box.
“I saw this clear stone shining back at me, and I looked and I held it in the light, and it was glowing at me, and I was like ‘Wow, I think I just found a diamond,’ ” Kelly said. The run also produced two-thirds of an once of gold. Gold is trading at $1,281 an ounce.
