“An authentic experience for diggers, by diggers”

Diamond Mountain offers an exclusive opportunity to dig for the rarest of the rare.

The Wilderness Dig Experience

Our Wilderness Digs offer a crystal prospecting experience in a shady, forest dig site.

The newly-opened Wilderness Dig sites at Diamond Mountain have been producing a diverse range of Herkimer diamond forms: large, smooth, traditional Herkimer diamonds, clusters, iron-included golden healers, high-quality water clear gems, and jet black hydrocarbon-included “black diamonds.” Layered skeletal crystals and black stem scepters and barbells, the rarest of all Herkimer forms, have also been unearthed at this level of the mountain! This is your exclusive chance to find types of crystals that cannot be found elsewhere in the Herkimer mining district!

Considered to be a “connoisseurs' mine,” Diamond Mountain is the place to visit if you are looking to dig rare Herkimer forms!

With our newly expanded dig sites, Diamond Mountain is now welcoming diggers of ALL AGES for this authentic Herkimer diamond mining experience!

The Digging

Herkimer diamonds form within pockets in solid dolomitic limestone ledge. The hardness of this limestone host rock makes mining them a highly physical and challenging process! The crystal-bearing layer in our Wilderness Dig sites sits close to the surface of the forest floor, which has exposed it to millions of years of elemental factors such as acidic rain, freezing and thawing cycles, as well as glacial activity. What this means for you is that the ledge itself is eroded and softer in comparison to the ledge in our lower Commercial Mines. Not only is the rock easier to break and move, but crystals have also eroded from their pockets and become dispersed randomly throughout the dirt! Whether you prefer digging through soil or the challenge of moving hard rock, digging in the forests of Diamond Mountain is a rockhound’s dream!

Helpful Tips:

  • Please expect to be self-sufficient and bring water and lunch—This is an independent dig experience: guides will help orient you in the morning, but will not stay with you for the entire day.

  • Your vehicle will be easily accessible throughout the day in nearby parking areas.

  • There is one bathroom (port-a-potty) provided at the check-in station.

  •  Accessibility: Our dig site is at the edge of a forest and about a 5 minute walk downhill on a gravel driveway from our parking area. There is one port-a-potty in our parking area near our check-in cabin that can be accessed throughout the day. In order to navigate our site, visitors should be comfortable walking on uneven surfaces and forest trails with roots and leaves. Closed-toe shoes with good tread are required.
