Diamond Hunting at the Ranch

Child's hand with Lake County diamond

I had clearly underestimated the project when our 9-year-old yelled “Mom, Dad, you have to help me get this diamond!” He had his toolbox packed (I should have seen this as a clue) and was marching down the driveway as he talked. We had plans to hike an area of the ranch with Lake County Diamonds (silicon dioxide crystals native to our region) that can be found on the ground, and he apparently had a specific gem in mind from an earlier exploration.

Lake County Diamonds appear in rocks shot from nearby volcanoes. The lava heats them up to melting, so they can be shaped like crystals or melted drops, but most are a combination of both. A few volcanic regions in the world contain gems like these, and our family’s Diamond Mine Vineyard at Six Sigma Ranch happens to be one of them. (This is the source of our Diamond Mine Red Blend available in the web shop.)  They can also be found in parts of Africa.

Most Lake County Diamonds are small and appear shining on the ground on farm roads (they emerge as traffic pulverizes the rocks they hide inside), but the specimen Caleb had in mind was not one of those. He had noticed it lodged inside a larger rock, and brought the tools to bust it loose. The result of his effort is pictured above.

Smaller Lake County Diamonds can be found with minimal effort on the 2-mile hike to our Diamond Mine Vineyard. You can find more information about hiking at the ranch here: www.SixSigmaRanch.com/visit

    I absolutely love diamond hunting! My kids & myself go all over the county trying to find new areas to hike to find them. We have so many we have found, but it never gets old. I would love to bring my kiddos and hike your ranch!
    Thank you,

Hello may I inquire about the cost of the diamond hunting on your beautiful ranch please?

    Terry, thank you for the note. We offer hiking at Six Sigma Ranch from 9am to 4pm daily. Details on the “Visit” page (and please check in and sign our liability release for at the Tasting Room). One of the hike routes starts at the tasting room and goes 2 miles to our “Diamond Mine Vineyard” where you can find the diamonds scattered on the ground. (you can read about it on the website, and also get the hiking guide at the tasting room). Also, we welcome guests to book our Saturday Vineyard Tours to the same location; the focus is wine, but it is possible to pick diamonds at the top of the vineyard on the tour also. – Christian

Hi I’m originally from lake county and hunted diamonds since the late 70s. I am visiting a friend right now and was wondering if there is access on short notice to visit your ranch which I’m so happy that you are opening your land for others to come and learn about the Moon tears. Love the beauty and history of lake county.

    Debbie, yes, we are happy to host you for hiking. Diamonds are a 1.7 mile hike from the tasting room, and we are open 7 days per week. Here are details on the $10 day pass and how to visit… https://sixsigmaranch.com/visit/
