Check current weather and road conditions before heading out, especially for remote BLM and Forest Service roads.
Where to Find Herkimer Diamonds in New York
Herkimer diamonds are doubly-terminated quartz crystals found in the Cambrian-age Little Falls Dolomite of Herkimer County and surrounding areas. They are not diamonds — they are exceptionally clear, naturally faceted quartz crystals with 18 faces (6 faces on each of two pyramidal terminations plus 6 prism faces). The clarity and natural "diamond" shape make them famous worldwide.
Top sites:
- Herkimer Diamond Mines, Middleville — Fee dig site. Crack open dolomite rock to find crystal-lined pockets. Tools available for rent. Excellent for families and beginners. Sedan access.
- Ace of Diamonds Mine, Middleville — Fee dig site. Similar dolomite collecting. Less crowded than the Herkimer Diamond Mines.
Herkimer diamonds form in vugs (cavities) within the dolomite. The rock is hard — a 3 lb crack hammer and cold chisels are standard. Split the dolomite along bedding planes to expose vugs lined with crystals. Most crystals are small (under 1/2 inch) but gem-clarity. Larger crystals (1+ inch) are less common. Some contain black hydrocarbon inclusions or water-filled enhydro inclusions — these are sought-after collector specimens.
Where to Find Garnet in New York
New York's Adirondack Mountains produce almandine garnets from the Gore Mountain area in Warren County. The garnets here are exceptionally large — crystals up to 6 inches in diameter occur in the garnet amphibolite. Gore Mountain is the type locality for a specific metamorphic reaction that produced these oversized garnets approximately 1 billion years ago.
Top sites:
- Barton Mines, Gore Mountain, North Creek — The world's largest garnet mine (industrial garnet for abrasives). Open for rockhounding (fee). Collect garnets from the mine dumps. Crystals range from thumbnail to fist-sized. Sedan access.
- Ruby Mountain, Warren County — Garnets in metamorphic rock on private land. Limited access.
Gore Mountain garnets are dark red-brown almandine, dodecahedral (12-sided), and heavily fractured internally. Gem-quality specimens are rare — most are opaque. They make excellent display specimens due to their size and crystal form. Bring a bucket — the mine dumps are productive and you can fill it quickly. Look for the dark red dodecahedra embedded in pale amphibolite matrix.
Where to Find Fossils in New York
New York's Devonian-age sedimentary rocks are rich in marine fossils. The Hamilton Group (shale and limestone) across central New York preserves trilobites, brachiopods, crinoids, corals, and bryozoans from approximately 380 million years ago. Penn Dixie Fossil Park near Buffalo is one of the best public fossil collecting sites in the country.
Top sites:
- Penn Dixie Fossil Park & Nature Reserve, Hamburg — Devonian marine fossils in shale. Trilobites (Phacops, Greenops), brachiopods, crinoids, and corals. Small fee. Tools and guidance provided. Open year-round.
- Utica area road cuts, Oneida County — Ordovician shale with graptolites and brachiopods. Surface collecting along road cuts.
Penn Dixie trilobites are the prize find. They are dark brown to black in gray shale, enrolled (curled up) or prone (flattened). Split the shale along bedding planes with a flat-head screwdriver — trilobites are preserved between layers. Work carefully: the cephalon (head) and pygidium (tail) often separate during splitting. Complete specimens are the goal.
New York Rockhounding Laws & Public Land Rules
BLM Land
New York has no BLM land.
National Forests
New York has no National Forest land. The Adirondack Park is a mix of state (Forest Preserve) and private land.
State Parks
Collecting is generally prohibited in New York state parks. The Adirondack Forest Preserve (state-owned land within the Adirondack Park) prohibits mineral collecting without a DEC permit.
Collection Limits
No state-wide collecting regulations for private land.
What's Protected
The New York State Constitution (Article XIV, Section 1) declares Adirondack and Catskill Forest Preserve land "forever wild" — no mineral removal without constitutional amendment or DEC authorization. Vertebrate fossils on state land require authorization.
The Herkimer diamond mines are the most visited collecting sites in New York. The Adirondacks have world-class minerals but access is highly restricted by the "forever wild" constitutional protection. Private land and fee dig sites are the primary collecting options. Penn Dixie is an excellent public fossil park near Buffalo.

Gear Checklist for Rock Hunting & Gem Mining in New York
What you need depends on the terrain and what you are collecting. Here is a general checklist for New York:
- Rock hammer (3 lb crack hammer for hard rock, geologist's pick for softer material)
- Safety glasses — required any time you swing a hammer
- Chisels — cold chisels for splitting seams and extracting crystals
- Bucket and bags — 5-gallon bucket, zip-lock bags for specimens
- GPS device or phone app — cell service is unreliable at most sites
- 1 gallon of water per person — minimum, more in summer
- Sturdy boots — ankle support for loose talus and mine tailings
- Field guide — a regional mineral identification guide for New York
Always respect private property, follow Leave No Trace principles, and check current regulations before collecting. On BLM land, the general rule is 25 lbs per day plus one specimen for personal, non-commercial use.
