Emerald Price Per Carat: What Kagem’s Auctions Show

There is no single “emerald price per carat” figure, because none of the world’s mineral or trade statistics agencies publish one — the US Geological Survey does not track emerald as a US commodity, and no Dutch or EU statistical office prices gemstones. The closest thing to a public benchmark is Gemfields’ Kagem mine in Zambia, which auctions its output roughly twice a year and discloses average price-per-carat by quality grade. At its most recent disclosed sale, higher-quality emerald averaged USD 146.08 per carat (May 2026 auction), while commercial-quality material averaged USD 9.72 per carat at the September 2026 auction, according to Gemfields and Rapaport. Retail fine-quality stones, which is what most 1-carat buyers are actually comparing prices against, run USD 1,000–5,000 per carat in 2026 per multiple gemstone dealers — a completely different number from the mine-gate averages, and the gap between the two is the single most important thing to understand before you compare any “emerald price” you find online.

That gap exists because auction averages are a blended figure across an entire parcel of rough and cut goods sold to wholesale dealers, while retail prices reflect a single polished, graded stone sold to an end consumer with cutting, certification, and margin layered on top. Both numbers are real. Neither one is “the” emerald price. This article gives you both, tells you which one applies to your question, and shows you exactly where to check for a fresher number when the next auction reports.

Current Emerald Price Per Carat: Auction Data vs. Retail Range

Start with the only recurring, disclosed data point in the industry. Gemfields Group’s Kagem Mining Limited, the world’s largest producer of responsibly sourced emeralds in Lufwanyama, Zambia, auctions its output several times a year and publishes average realized price per carat by quality grade afterward. Kagem accounted for 25% of global emerald production in 2024 and produced 40.3 million carats of combined emerald and beryl that year, per Gemfields Group’s own mine data. Since its first sale in July 2009, Kagem’s 51 auctions have generated USD 1.1 billion in aggregate revenue — the deepest public price history the emerald trade has.

Here is what those auctions actually printed, tier by tier:

• Higher-quality emerald, May 2026 auction: USD 146.08 per carat average (Gemfields Group).
• Higher-quality emerald, September 2025 auction: USD 160.78 per carat average (Gemfields Group) — a decline of roughly 9% into the May 2026 sale.
• Commercial-quality emerald, September 2026 auction: USD 9.72 per carat average (Rapaport/Gemfields) — described by Rapaport as an improvement over the prior commercial sale.
• Commercial-quality emerald, December 2025 auction: USD 7.46 per carat average (Gemfields Group).

Two things jump out. First, the spread between commercial and higher-quality lots at the same mine, in the same window, is roughly 15-to-1 — that is the clearest evidence available that “emerald price per carat” is meaningless without a quality qualifier attached. Second, the higher-quality tier moved down between September 2025 and May 2026 while the commercial tier moved up between December 2025 and September 2026 — the two tiers are not tracking each other, so a headline about “emerald prices rising” or “falling” is only ever describing one slice of the market.

None of these are retail prices — they are wholesale, mine-gate averages paid by dealers buying entire lots of rough and cut goods sight-unseen or via limited preview. What a consumer pays for a single graded, polished stone is a different number entirely. For 2026, gemstone dealers place fine-quality natural emerald retail pricing at USD 1,000–5,000 per carat, and commercial-grade natural emerald retail pricing at USD 300–1,000 per carat, according to multiple retailer sources including AfricaGems and AltGems. Separately, market analysis from AfricaGems puts the increase in high-grade emerald pricing since late 2024 at 22%, and estimates that unenhanced (untreated) emeralds carry a 45% premium over treated stones of comparable visual quality in 2026.

• ✔ Commercial-quality goods sit near $7–$10/carat at the mine gate, $300–$1,000/carat at retail.
• 📊 Higher-quality mine lots sit near $146–$161/carat at the mine gate — still far below retail fine-stone pricing because most of that lot is still rough, uncut, and unsorted for the top grade.
• ⚠ Retail fine and investment stones reach $1,000–$5,000/carat, and exceptional single stones go higher still, per dealer guidance.
• 🌍 Origin premiums apply on top of grade, not instead of it.
• 🔍 Untreated stones carry a documented 45% premium over treated stones of similar visual quality (AfricaGems, 2026).

Comparison Table: Price Per Carat by Quality Tier, Source, and Date

The table below puts every verified figure in this brief side by side so you can see which number applies to your situation — mine-gate auction average, retail commercial, or retail fine — without having to cross-reference five articles.

Read this table left to right, not top to bottom, for any single figure — the columns tell you what the number actually represents, which is the piece most articles strip out. A $9.72/carat headline and a $9,000/carat headline can both be accurate “emerald prices” published the same month; they are describing different objects entirely.

1-Carat Emerald Pricing, Specifically

Because “1 carat” is one of the most common qualifiers attached to emerald price searches, it deserves its own section rather than a buried mention. A 1-carat emerald’s price depends almost entirely on which quality tier it falls into, not its weight — weight only sets the multiplier.

• Commercial 1-carat stone: roughly $300–$1,000 total, using the retail commercial-grade range from AltGems (2026).
• Fine 1-carat stone, unspecified origin: roughly $1,000–$5,000 total, using the retail fine-quality range from AfricaGems and other dealers (2026).
• Fine 1-carat Zambian stone: projected at $4,000–$9,000, per AfricaGems’ 2026 origin-specific guidance.
• Fine 1-carat Colombian stone: projected at $8,500–$16,000, per Colonial Gemstones’ 2026 origin-based analysis.

Notice the Colombian range sits nearly double the Zambian range at the same “fine” grade label — that is origin premium doing its work, and it is why two “fine 1-carat emeralds” can carry an $8,000 price gap even when a buyer cannot see a visual difference without a lab report. Ask any seller for the stone’s origin report and treatment disclosure before comparing it to either range above; without those two documents, “1 carat, fine quality” is not enough information to know which end of a $300–$16,000 span you are looking at.

Emerald Price Context for US and Netherlands Buyers

If you are pricing an emerald from the United States or the Netherlands, two structural facts shape how you’ll actually find a number.

In the United States: emeralds are not a domestically produced mineral commodity at meaningful scale — the US Geological Survey’s mineral commodity reporting (published annually as the Mineral Commodity Summaries) covers only synthetic gem material made domestically, not natural emerald mining or pricing. That means there is no USGS price series to check, unlike, say, copper or gold. US buyers and dealers rely entirely on the international auction and dealer network described above — Gemfields’ Kagem results, Rapaport’s trade reporting, and retailer price guides are the practical substitutes for a government statistic that does not exist for this stone.

In the Netherlands and the wider EU: the same gap applies. Eurostat and national statistical offices do not track gemstone commodity pricing the way they track agricultural or industrial mineral prices. A Dutch buyer sourcing emerald — whether for jewelry retail, appraisal, or import — is working from the identical international reference points as a US buyer: Kagem auction disclosures, Rapaport, and dealer guides, adjusted to euros at the prevailing EUR/USD rate on the day of purchase or valuation.

Practically, this means the discipline that matters most for US and Netherlands buyers is the same one appraisers already use for diamonds: get a gemological report (naming treatment status and, where determinable, likely origin) before accepting any per-carat figure as applicable to your stone, since none of the ranges above are enforceable price lists — they are market observations from a specific window in 2026.

“A 15-to-1 gap between commercial and higher-quality Kagem lots is the emerald market’s real headline — not any single average.“

What Actually Moves the Price

1) Supply out of a small number of mines

Kagem alone accounts for roughly a quarter of global emerald production by Gemfields’ own 2024 figure, which means one mine’s auction calendar has an outsized effect on any published “market price.” Colombia’s Boyacá region — historically the source of the trade’s most prestigious stones — saw output decline by 14% in 2025, per market analysis cited by AfricaGems. A supply drop concentrated in the origin carrying the highest prestige premium tightens exactly the segment buyers are least price-sensitive about, which is part of why higher-quality material has held a premium even as commercial-grade softened.

New supply is also slow to arrive. Emerald deposits are geologically selective — a mine can increase total carats extracted while the share of gem-quality, sellable-at-premium material stays flat or falls, because grade is a function of where in the deposit the rough comes from, not how much is dug. This is why total production tonnage is a poor predictor of price; the auction disclosures above, sorted by grade, are a far better one.

2) Quality still explains most of the spread

Color saturation, transparency, and inclusion load explain the 15-to-1 gap between Kagem’s commercial and higher-quality tiers far more than any other single variable. A buyer comparing two “1-carat emeralds” without a grading report is really comparing two different products that happen to share a weight unit.

3) Treatment disclosure moves price directly

AfricaGems’ 2026 analysis puts the premium for unenhanced (untreated) emeralds at 45% over treated stones of comparable visual quality. Nearly all emeralds on the market receive some clarity-enhancing oil or resin treatment; a report confirming minimal or no treatment is one of the few single facts that reliably shifts a stone’s price by nearly half, independent of color or origin.

4) Origin carries a premium, but only on top of grade

The 1-carat fine-stone projections above — $8,500–$16,000 for Colombian versus $4,000–$9,000 for Zambian — show origin adding roughly 80–100% at the same quality label. Origin does not rescue a poorly colored or heavily included stone; it amplifies a stone that already qualifies as fine.

5) Currency and macro conditions set the frame dealers price into

Auction results are denominated in US dollars, so a stronger or weaker dollar changes what a euro-denominated Dutch buyer or a Zambia-based seller actually realizes even if the dollar-per-carat figure is unchanged. Neither the brief nor any public source in this evidence base quantifies a specific currency effect on emerald pricing for 2026 — if you need that number, the method is to compare the auction date’s EUR/USD or relevant spot rate directly against your own purchase currency, rather than relying on a gemstone-specific inflation index, because none exists.

Origin Analysis: Why Colombian, Zambian, Brazilian, and Ethiopian Emeralds Trade Differently

Colombian emeralds

Colombian material, historically centered on the Boyacá region, remains the benchmark most buyers compare everything else against. The 1-carat fine-stone projection for Colombian origin — $8,500–$16,000 — is roughly the top of the entire retail range cited in this brief, and it holds that position even with 2025’s 14% regional output decline factored in, per AfricaGems’ analysis. If anything, tighter Boyacá supply should reinforce rather than erode that premium in the near term, since demand for documented Colombian origin has not shown a corresponding drop in the sources reviewed here.

Zambian emeralds

Zambia, via Kagem, is the source of the only recurring public price data in this article. Kagem’s 25% global production share and its 51-auction, $1.1 billion track record since 2009 make Zambian material the best-documented origin in the trade, even though its 1-carat fine-stone projection ($4,000–$9,000) sits below Colombian at the same grade label. For buyers who want traceability over prestige, Zambian origin currently offers more verifiable auction history per dollar than any competing source in this evidence base.

Brazilian emeralds

Brazilian production spans a wide quality range and supports mid-tier volume in the broader market. No auction-level pricing disclosure comparable to Kagem’s exists in this brief for Brazilian material; buyers should request grading and origin documentation rather than relying on origin name alone, and treat any Brazilian per-carat quote as needing the same treatment-status and grade verification as any other origin.

Ethiopian emeralds

Ethiopian material remains a newer entrant in buyer perception. No disclosed auction or retail range specific to Ethiopian origin appears in the sources gathered for this brief — where a seller quotes an Ethiopian-origin price, ask for the same grading and treatment paperwork you’d require of any other origin, since there is no public benchmark yet to check it against.

Calculator: Estimate a Parcel’s Value by Quality Mix

Because the commercial and higher-quality Kagem tiers sit roughly 15-to-1 apart, the single most useful thing a buyer, appraiser, or small-lot dealer can do is estimate blended value from the actual mix of grades in a parcel, rather than quoting one average for the whole lot. Enter a parcel’s total carat weight and the estimated share that is higher-quality versus commercial-quality, using the two most recent disclosed Kagem averages as your per-carat inputs, and adjust either price field if you have a more current auction result.

Assumes only two grade bands and no treatment, size, or origin adjustment — real parcels usually contain a continuous quality spread, and any single stone’s retail value will differ further based on cut, certification, and buyer channel. Default per-carat prices are Kagem’s May 2026 (higher-quality) and September 2026 (commercial) auction averages; replace them with a newer auction result once one is published.

Why Mining, Land Use, and Infrastructure Matter to the Price

Emerald pricing is downstream of extraction conditions in ways that rarely make it into per-carat headlines. Kagem’s scale — a quarter of world supply from one mine — exists because Zambia’s Copperbelt-adjacent infrastructure supports large-scale, mechanized extraction; smaller artisanal operations elsewhere face different cost structures entirely, which is part of why commercial-grade material from less mechanized sources can price differently even at the same nominal quality grade.

Land use and permitting

Emerald extraction often occurs in ecologically sensitive or logistically difficult terrain. Predictable permitting frameworks reduce the project delays that tighten supply and raise short-term prices, while inconsistent permitting deters the capital investment that would otherwise expand supply and stabilize prices over time. Both outcomes show up eventually in auction results like the ones tracked in this article.

Infrastructure and regional development

Roads, power, and water management directly affect extraction and processing costs, which flow through to the price a mine needs to realize per carat to stay viable. Weak infrastructure in a producing region raises the cost floor under even commercial-grade material; strong infrastructure — of the kind that supports Kagem’s auction cadence — is part of why Zambian output has the most complete public price history of any origin covered here.

Environmental stewardship and buyer confidence

Buyers increasingly weight traceable, environmentally documented supply chains alongside color and clarity, which is part of the mechanism behind the 45% untreated-stone premium and the broader shift toward origin-plus-verification pricing that AfricaGems describes in its 2026 analysis. A mine’s environmental and labor practices are no longer separable from its stones’ commercial ceiling.

How Farmonaut Supports Modern Mineral Exploration Intelligence

As mining costs rise and environmental scrutiny intensifies, early-stage exploration decisions matter more than ever — including for colored-gemstone jurisdictions where the same permitting and land-use pressures described above apply. Farmonaut is a satellite data analytics company that applies Earth observation, remote sensing, and artificial intelligence to modernize mineral exploration worldwide. While the company is widely recognized in agriculture, forestry, wildfire monitoring, and product traceability, its mineral intelligence capabilities are directly relevant to producers and explorers weighing where the next deposit — gemstone or otherwise — is worth pursuing.

At Farmonaut, we focus on satellite-based mineral intelligence that helps exploration teams screen large areas faster and more objectively before expensive field campaigns begin. Our approach uses multispectral and hyperspectral satellite data to analyze reflected electromagnetic energy from the Earth’s surface, enabling identification of mineralized target zones, alteration halos, faults, fractures, and geological patterns associated with potentially viable deposits.

Traditional exploration is slow, expensive, and often disruptive — it relies on ground surveys, trenching, geochemical sampling, and exploratory drilling. By contrast, at Farmonaut, we use satellite imagery and AI-driven analysis to reduce exploration timelines from months to days, lower early-stage costs by up to 80–85%, and avoid environmental disturbance during the initial exploration phase.

This matters for gemstone-linked jurisdictions even when the immediate target mineral differs from emerald specifically. Better prospect validation, lower wasted drilling, and improved targeting help operators make smarter investment and licensing decisions, and align with ESG-focused stakeholders who want more responsible exploration methods before full extraction begins. In a market where premium emerald pricing increasingly depends on sustainable extraction and transparent supply chains — as the 45% untreated-stone premium and Kagem’s own sustainability positioning both suggest — upstream geospatial intelligence supports better decisions long before production starts.

At Farmonaut, we provide structured reporting designed for technical and commercial users. The Premium mineral intelligence report includes high-potential target zones, prospectivity heatmaps, estimated mineral location and depth ranges, indicative quantity assessments, and geological interpretations. The Premium+ report adds TargetMax™ Drilling Intelligence, including optimal drilling angle recommendations and interactive 3D subsurface models to support next-step planning.

How to Get a Fresher Number Than This Article

Every price cited above has a shelf life, and this article’s real value beyond the numbers is telling you exactly where to look when they age out.

1. For the next Kagem auction result: Gemfields publishes mine and auction data on its own site; check the Kagem mine page at Gemfields Group’s Kagem mine page for the next scheduled sale date and the realized price-per-carat for both commercial and higher-quality lots. Auctions run roughly twice yearly; this article’s most recent data point is the September 2026 commercial sale and the May 2026 higher-quality sale.
2. For independent confirmation and trade commentary on the same auctions: Rapaport’s coverage of Gemfields auction results is the trade’s standard secondary source and typically adds context Gemfields’ own release does not, such as buyer sentiment and comparison to the prior sale.
3. For US mineral production context (not retail pricing): the USGS Mineral Commodity Summaries, published annually, is the authoritative US government reference — but as noted above, it does not carry a natural emerald pricing line, only synthetic gem material. Check the current edition at USGS’s publication portal if you need to confirm this remains the case.
4. For retail range updates: AfricaGems and AltGems both publish periodically updated guides; treat any figure from either as dated to its publication month and re-check before quoting it as current — this article’s retail ranges are sourced to AfricaGems’ 2026 collectors’ guide.

The durable method, regardless of when you’re reading this: find the most recent Kagem auction’s disclosed average for the grade tier you care about, confirm whether you need a mine-gate or retail figure, and check treatment/origin documentation before applying any origin premium from this article’s table. That sequence does not expire even when every number in it eventually does.

FAQ: Emerald Price Per Carat

Final Thoughts

The most useful thing this article can leave you with is not a single price but a method: identify which of the two markets — mine-gate auction or single-stone retail — your question is actually about, find the grade tier that matches your stone, and confirm treatment and origin before applying any premium. Kagem’s disclosed auction history, running from $7.46/carat commercial to $160.78/carat higher-quality across its 2025–2026 sales, remains the trade’s only recurring public benchmark, and checking its next result directly at Gemfields’ own mine page will always beat relying on a secondhand summary, including this one.
