🔔 Breaking news — GIA/Gübelin officially confirms Ethiopia as a new production area

📢
GIA & Gübelin Gem Lab jointly identify copper-bearing tourmaline from Ethiopia
By 2026, we will be a world-class gem identification organization.GIA (Gemological Institute of America)andGübelin Gem Lab (Switzerland)Guji zone, Oromia region, southern Ethiopia.AbulooWe have scientifically confirmed that copper-containing tourmaline is produced in the surrounding area.

In May 2026, Gübelin detected a sample that did not match the chemical composition pattern of existing production areas (Brazil, Mozambique, and Nigeria). GIA also started a full-scale investigation in June, and by JulyOver 100 rough and faceted stonesAs a result of the analysis, it was confirmed that Ethiopia is a new source of Paraiba-type tourmaline.

SECTION 02

Timeline from discovery to official confirmation

Paraiba tourmaline from Ethiopia did not appear on the scene overnight. Even before the official confirmation by the identification agency, local mining officials, some collectors, and specialized buyers had been working to gather information and secure samples, and scientific verification by the identification agency has since progressed.

Paraiba tourmaline from Ethiopia — the journey from discovery to official confirmation
Early 2025~
Some collectors and professional buyers conduct on-site inspections. — According to market information that Selby had obtained from related parties, some collectors and specialized buyers were visiting Ethiopia from this period to secure rough stones and conduct their own analysis.*The 2025 trends described here are not official announcements by identification organizations, but include market information obtained through Selby's network.
May 2026
Gübelin detects anomalies — Confirmed that the chemical composition of the samples brought to Gübelin Gem Lab does not match any pattern from Brazil, Mozambique, or Nigeria. An identification report points out the possibility of a new production area in Ethiopia.
June-July 2026
GIA begins full-scale investigation — Launched systematic investigation of samples declared as “Ethiopian”. by july100 points or moreReceived and analyzed rough and faceted stones. Chemical analysis was performed by LA-ICP-MS and EDXRF.
From around August 2026
Information gradually surfaces in the secondary market —Although belatedly, as more and more Japanese companies enter the market, copper-containing tourmalines believed to be produced in Ethiopia are increasingly being seen at international jewelry markets and jewelry shows.
September 2026
Peer-reviewed paper published in MDPI Minerals — "Copper-Bearing ('Paraíba') Tourmaline from Abuloo, Ethiopia: Preliminary Results" published in MDPI Minerals 16(9).GIA officially adds "Ethiopia" to the country of origin column in its report.

Supervisor comment — Takazo Saito (Selby)

"Selby's network has been gaining information on collectors and professional buyers who have been working to secure and analyze rough stones in Ethiopia since around 2025. These movements were market information before the official confirmation by identification organizations, and we believe that official support has finally been established with the publication of scientific confirmation by GIA and Gübelin in 2026. It is important to understand the field information and official announcements by identification organizations separately when looking at the market."

SECTION 03

Geological background of the Abuloo deposit

A paper in MDPI Minerals reveals the source of Paraiba tourmaline from Ethiopia.Near Abuloo, Guji Zone, Oromia Region, Southern EthiopiaIt became clear that.

Overview of Abuloo deposit
🇪🇹 Southern Ethiopia Guji Zone, Oromia Region 📍 Abuloo Genale River Alluvial / Placer Features of the deposit 📐 Production type Alluvial deposits (river deposits in the Genare River basin) 💎 Form of production Boulders and alluvial sand (due to weathering and transport from original rock) Reports of rough stones over 40ct 🎨 Confirmed hue Vivid blue ~ bluish green Violet, purple, and colorless zoning in some areas 🔬 Mineral species Elbaite (Lithian tourmaline) — Cu-containing

Source: MDPI Minerals 16(9), 964 (2026) — "Copper-Bearing ('Paraíba') Tourmaline from Abuloo, Ethiopia"

It should be noted thatAlluvial deposit (alluvial/placer)The point is that it is produced from. This pattern is similar to early mining in Mozambique, and primary deposits (pegmatites) have not yet been confirmed. If primary deposits are discovered, supply may fluctuate significantly.

SECTION 04

Chemical fingerprint from Ethiopia — new identification factors: V, Pb, and Ga

According to GIA/Gübelin analysis and an article in MDPI Minerals, copper-bearing tourmaline from Ethiopia hasCharacteristic chemical composition pattern that is effective for distinguishing from existing production areashas been confirmed.

Three chemical markers that identify Ethiopian origin
🇪🇹 Made in Ethiopia Chemical fingerprint Cu max ~2.29 wt% V (vanadium) > 60 ppm Significantly higher than other production areas → Important indicators for determining origin Pb (lead) 170-6,000 ppm Extremely wide range → Significant difference from other production areas Ga (Gallium) 280~900 ppm High concentration area compared to other production areas → Identification of production area by three-element complex Source: GIA News & Press (2026) / MDPI Minerals 16(9), 964 (2026)

Copper content — up to ~2.29 wt% Cu

According to the MDPI paper, the copper content of samples from Abuloo isUp to about 2.29 wt% CuIt is reported that. While there are samples that are copper-rich and meet the definition of Paraiba Tourmaline,Not all copper-containing tourmalines from Abuloo are classified as "Paraiba tourmaline".Color, coloring factors, chemical composition, etc. must be checked individually.

Hue variations

The confirmed hue isBright blue to bluish greenThere are samples that have the "neon feel" that is required of Paraiba tourmaline. However,Violet/purple/colorless zoningThere have also been reports of samples showing this, indicating that there are large individual differences in quality.

🔬
Why are V, Pb, and Ga effective for identifying production areas?

In identifying the origin of gemstones, we use not only the main coloring elements (Cu, Mn, Fe), but alsoPatterns of trace elementswill be a crucial clue. The content ratio of vanadium, lead, and gallium varies depending on the production area as it reflects the geological environment of the ore deposit. In addition to these three elements, GIA uses multivariate analysis that includes Bi (bismuth), Zn (zinc), and rare earth elements (REE) to distinguish Ethiopian products from Brazil, Mozambique, and Nigeria.

Important updates since the previous article

In the previous article, we treated the product as ``investigation in progress'' because there was limited public information about the Ethiopian product. In 2026, with confirmation by GIA and Gübelin and publication of MDPI paper,Quantitative data of Cu up to ~2.29 wt%Ya,Elemental compositions such as V, Pb, and Ga are effective for identifying production areas.was shown more specifically. However, as the paper itself states as "Preliminary Results," the numbers and identification criteria may be updated in additional research in the future.

Status of response to Ethiopian products by major identification organizations [as of September 2026]
GIA Gemological Institute of America ✅ Officially supported • "Ethiopia" officially added to production area report • Over 100 samples analyzed • Building a classification system using LA-ICP-MS + EDXRF Gübelin Switzerland, Gübelin Gem Lab ✅ Officially supported • Anomaly detected and investigation started in May 2026 • Joint confirmation with GIA • Updated production area determination algorithm SSEF Swiss Gem Research Institute 🔄 We are strengthening our response • First possible report in 2024 • Analyzing samples that cannot be attributed to existing production areas • Refinement of discrimination method in progress 📌 Suggestions for consumers GIA report mentions "Ethiopia" as country of origin Now available, buyers can In addition to the "Identification document with the place of origin" Ask has become important. → Now is the time to improve the transparency of production areas Now is the time to use the identification book.
SECTION 07

Impact on the market — will prices fall?

Confirmation of a new production area tends to lead to the view that ``the supply of Paraiba will increase and the price will fall.'' However, at present, there are many uncertainties regarding the supply amount, quality composition, and continued mining scale of Ethiopian production.It is not yet possible to determine the short-term price impact.The following is a discussion on market structure based on currently available information.

Structural analysis of price impact
🔽 Supply is narrowed down by the funnel Alluvial deposits → wide variation in quality With hue zoning → Uneven cut quality Part of the total production is Paraiba certified products 📈 Demand continues to grow Worldwide popularity of Paraiba is increasing year by year Produced in Paraiba, Brazil, almost exhausted The topic of new production areas expands the interest of the entire market 🔬 Quality evaluation on an individual basis Cu content, neon feel, and transparency vary from stone to stone It is inappropriate to judge the value of "Produced in Ethiopia" all at once High quality specimens are comparable to those from Brazil and Mozambique ⛏️ Primary deposits have not been discovered Currently, only alluvial deposits have been confirmed Possibility of fluctuation in supply amount when primary deposits are discovered Long-term supply stability is unknown 📊 Current conclusion Official confirmation of Ethiopian production will contribute to improving market transparency, but It is unlikely that the overall price of Paraiba will collapse in the short term
💎
Supervisor comment — Takazo Saito (Selby)

"As far as I have confirmed through Selby's network, there are high-quality stones with a strong neon feel from Abuloo. On the other hand, there are individual differences in color, transparency, and chemical composition, so it is difficult to judge the value all by the name of the place of origin. The increased transparency of production areas through confirmation by GIA and Gübelin is a major step forward for the market.We believe that evaluations will continue to be made based on changes in supply, the presence of primary deposits, and new research results.

SECTION 08

What consumers should do now — make informed decisions

Now that Ethiopian production has officially been added, we will once again summarize the points that consumers should keep in mind when purchasing Paraiba tourmaline.

2026 Edition Paraiba Tourmaline Purchase Guide
1 Be sure to check the identification document that states the place of origin Now that GIA has officially added "Ethiopia", the transparency of production areas has improved significantly. Please check whether the country of origin is clearly stated on the identification document. 2 Note the difference in spelling between "Paraíba Tourmaline" and "Copper-bearing Tourmaline" Even if copper is detected, it will not be listed as "Paraiba" unless the identification criteria are met. The difference in notation greatly affects the price. 3 Don't judge the value just by the name of the place of origin Evaluate the product based on the quality of the product (color, clarity, neon feel, size) rather than "it's expensive because it's from Brazil" or "cheap because it's from Ethiopia". 4 Check whether there is any processing (heating, etc.) The processing status of Ethiopian products is still under investigation. Be sure to check the treatment column on the identification report and confirm that it shows "No indication of heating." 5 Check the seller's professionalism and procurement transparency The best defense is to purchase from a specialized company that can explain in detail the basis of production location information, identification implementation system, and local network. 6 Continuous access to new information Ethiopian production is still at the "Preliminary" stage. Continuously access updates on upcoming papers and identification institutions, and make decisions based on the latest information. Correct knowledge and reliable identification documents - these are the biggest weapons for consumers.
⚖️
From a consumer protection perspective

Paraiba tourmaline is an expensive gemstone, and its market price can vary widely depending on its origin. GIA's addition of Ethiopia to its production area reportCreating an environment where consumers can make decisions based on correct informationThis is a very important development in that respect. Sellers are also required to take more responsibility than ever to accurately disclose information on the country of origin.
