Hallelujah Junction Mine: Amethyst, Jackson & JXR Guide

The Hallelujah Junction amethyst mine sits in Lassen County, northeastern California, near the California–Nevada state line, and currently operates as a fee-dig rockhounding site rather than a commercial gemstone operation. Jackson’s Crossroads amethyst mine (Wilkes County, Georgia) and the JXR amethyst mine are separate, smaller-scale deposits that get folded into the same search queries because all three sell amethyst specimens directly to collectors and diggers rather than through wholesale channels. None of the three publishes an annual production figure — that gap matters, and this guide tells you exactly where to look instead of guessing at a number.

If you searched for “hallelujah junction mining,” “hallelujah junction amethyst,” “hallelujah mines,” or “hallelujah junction crystals,” you’re looking for the same site: a working amethyst claim that takes booked digging visits and sells rough and cut material. If you searched for “jxr amethyst mine,” you’re looking at a smaller producer whose output is even less publicly documented. This page treats each mine on its own terms and gives you the actual USGS national data that exists, rather than inventing site-specific numbers that were never published.

Hallelujah Junction Mine: Location, Access & Crystals

Hallelujah Junction is a geode-and-vein amethyst deposit formed in volcanic host rock typical of the northern Sierra Nevada boundary zone, where iron and manganese trace elements combined with natural irradiation produced the purple coloration diggers find in pockets and lined cavities. The mine’s own booking channel — its Instagram account — is the most current source for whether digging slots are open in a given month, since the operation runs on a scheduled fee-dig basis rather than continuous extraction. Check the mine’s Instagram directly before planning a visit; availability changes seasonally and is not published anywhere else.

What the mine does NOT publish, and what no government or industry source discloses either, is an annual tonnage or dollar output figure specific to Hallelujah Junction. This is a genuine reporting gap, not an oversight on our part — the US Geological Survey aggregates all domestic amethyst and quartz-variety production into a single “macrocrystalline quartz” category at the national level, so no mine-by-mine breakdown exists in public data. If you need a defensible production estimate for this specific site, the only path is to contact the operator directly through their booking channel and ask what they’re willing to disclose.

That decline is the real story sitting behind these queries: US gemstone production value, across all gem types, fell from $99 million in 2023 to $47 million in 2025 — a drop of roughly 30% in a single year, per the USGS Mineral Commodity Summaries. Small fee-dig operations like Hallelujah Junction are the segment absorbing that volatility most directly, since they depend on visitor volume and specimen sales rather than industrial offtake contracts. Farmonaut’s satellite platform is built for tracking land-surface change at mineral sites like this — useful context if you’re evaluating claim boundaries, vegetation recovery on old workings, or access-road conditions before a trip.

Jackson’s Crossroads and JXR Amethyst Mine

Jackson’s Crossroads amethyst mine, often shortened to “Jackson amethyst mine” in search traffic, and marketed under the JXR name in some retail listings, operates from a deposit in Wilkes County, Georgia — geologically distinct from the Sierra Nevada setting at Hallelujah Junction. The site is known among collectors for well-formed scepter and cathedral-style amethyst crystals, and like Hallelujah Junction, it sells primarily through direct specimen sales and scheduled digging rather than bulk industrial channels.

The operator’s website (jxramethyst.com) updates specimen availability and any digging-day schedule seasonally, but — matching the pattern at Hallelujah Junction — it does not disclose annual production volume or dollar value. That’s consistent across nearly every small US gemstone operation: production data at this scale simply isn’t required to be reported to any state or federal agency, unlike coal, metals, or industrial minerals, which carry MSHA and state reporting obligations. If a number for either mine’s output ever appears in a directory or listicle online, treat it as unsourced unless it links back to the operator itself.

Mining and forestry activity intersect with agricultural land use in both Lassen County and Wilkes County in ways that matter for anyone evaluating a claim or adjacent farmland — road access built for mine traffic, water table effects, and reclamation status of worked-out pits all carry over into land value for neighboring agricultural use.

What USGS Actually Reports on US Gemstone Production

Here is the durable method for checking these numbers yourself, since USGS refreshes this dataset roughly on an annual cycle: pull the current-year Mineral Commodity Summaries gemstones chapter directly from USGS. The 2026 edition puts total US gemstone production value, across all gem types combined, at $47 million for 2025 — down from $99 million in 2023 per the 2024 edition. Six states account for the large majority of that output: Arizona, Oregon, California, Nevada, Montana, and Maine together represent 68% of national gemstone production value in the 2024–2025 reporting period.

Amethyst itself is classified by USGS as “macrocrystalline quartz,” a category that also absorbs citrine, smoky quartz, and other coarse-crystal quartz varieties. That means there is no published breakout of amethyst-only production value, no separate state ranking for amethyst specifically, and no export or import trade-flow data broken out by gemstone type at all — USGS does not publish gem-level trade statistics. If your research needs an amethyst-specific figure rather than the blended quartz category, that figure does not exist in public federal data; the closest defensible substitute is the macrocrystalline quartz total, clearly labeled as such.

To pull an updated version of this yourself next year: search “USGS Mineral Commodity Summaries gemstones” for the current edition, which supersedes the 2026 PDF cited here once released. The report is published annually and is the only federal source with state-level detail on this industry.

Comparison Table: Hallelujah Junction vs. Jackson’s vs. JXR

Every “estimated annual yield in tons” figure you may have seen attached to these three mines elsewhere online is unsourced. None of the three discloses tonnage, and USGS does not track them individually — it only tracks the aggregated national quartz-gemstone category described above. We are not publishing invented tonnage numbers in their place; the table above shows what is actually knowable about each site today.

The “Post-Mining Interactive Framework, Figure 1” Search — What It Points To

A separate cluster of searches lands here looking for an “interactive framework, Figure 1” tied to “post-mining” land use — phrasing that matches academic reclamation and multi-hazard risk-assessment literature (frameworks such as TRIM4Post-Mining and related MDPI Safety-journal papers on post-mining site risk). We checked specifically for a published study connecting that framework to Hallelujah Junction, Jackson’s Crossroads, or JXR, and found none: no reclamation plan, environmental study, or site-specific “Figure 1” interactive framework tied to any of these three amethyst operations exists in the material available to us. If you arrived here searching that phrase expecting mine-specific reclamation data, it is not published for these sites.

What we can tell you accurately: reclamation and post-mining land-use planning for small fee-dig gemstone operations in the US is governed at the state level (through each state’s mined-land reclamation act or equivalent), not by a single federal framework, and disclosure requirements vary by state and claim type. If you’re researching the academic “post-mining interactive framework” literature itself rather than these specific mines, that framework lives in the peer-reviewed safety and reclamation-planning literature — search it directly by its published title rather than through a mining-company site, since no operator page will host it.

Amethyst Pricing by Grade: What a Specimen Is Worth

Retail amethyst pricing runs from $2 to $60 per carat depending on quality grade, according to 2026 market data compiled by GemVal. That’s an enormous range for a single gem variety, and the grade differences driving it are concrete: color saturation (pale lavender vs. deep “Siberian” violet), clarity (eye-clean vs. included), and cut quality all move a stone across that range. A rough, uncut specimen straight from a fee-dig bucket sits well below the $2/carat floor in practical terms — that price band applies to cut, graded material, not rough.

Check GemVal’s amethyst price chart directly for the current month’s figures if you’re pricing a specific stone — the chart is republished on a rolling basis, typically within a 30-day window, and lets you filter by carat weight and grade rather than relying on a single blended figure. Since neither Hallelujah Junction nor Jackson’s Crossroads publishes a specimen price list publicly beyond what’s shown at time of sale, GemVal’s grade-based chart is the best available proxy for what material from either site would fetch once cut and graded.

Fee-Dig Trip Cost Calculator

Use this to estimate what a bucket of rough amethyst from a fee-dig visit could be worth once cut, based on the $2–$60/carat retail range above — enter your own dig fee, expected rough weight, and the grade you think it’ll cut to.

Assumptions: uses GemVal's 2026 published $2–$60/carat retail grade bands as the price inputs; excludes travel cost to the mine, tool/equipment rental, and any resale commission. It does not estimate how much rough material a given dig fee will actually yield — that varies by site and by luck, and is not something a calculator can predict.

Satellite Monitoring for Mine Sites and Surrounding Land

Beyond pricing and production data, anyone evaluating land near a gemstone claim — whether for a farming operation, a forestry lease, or a second mining claim — benefits from remote-sensing tools that track surface change over time without a site visit. Farmonaut's platform applies this to both mining and agricultural land:

• Satellite-based land monitoring: track vegetation health and surface disturbance on and around claims via Farmonaut's satellite platform.
• Traceability: blockchain-based traceability tools for tracking origin and chain-of-custody on mineral or farm products moving through a supply chain.
• Carbon footprint tracking: carbon footprinting tools for operators reporting on reclamation or emissions.
• Fleet management: vehicle and equipment tracking for sites running transport between a claim and processing or sale points.
• Financing verification: crop loan and insurance verification tools for lenders evaluating adjacent farmland.
• Large-area management: the agro-admin app for operators managing multiple parcels or claims at scale.

Technical teams building their own dashboards can pull this data directly through the Farmonaut API, documented in full in the developer docs.

Getting a Fresher Number Than This Page Has

Everything time-sensitive in this guide carries a named source and a refresh path on purpose: USGS reissues the Mineral Commodity Summaries gemstones chapter annually, GemVal republishes its amethyst price chart on a rolling basis within about 30 days, and each mine's own booking channel is the only accurate source for whether digging is currently open. None of the three mines discloses production volume, and that gap is unlikely to close — small fee-dig operations face no reporting requirement that would force it. If you need a number this page doesn't have, the fastest path is to ask the operator directly rather than trust an aggregator site repeating an old figure.
