ANTANANARIVO, Nov 19 (Epicstorian News) – Madagascar’s interim president displayed a 300 kg gemstone found in the presidential palace, officials said.

Colonel Michael Randrianirina, standing beside the find, called it “a national asset”.

“It might be sold, and it will be up to the minister to explain the procedures,” he said.

He added officials would ensure “complete transparency” in handling the gemstone.

The interim president, who seized power last month, attended the presentation but offered no comments.

Uncertainty Around Discovery Location and Timing

Colonel Randrianirina did not provide details on when or why the stone was placed in the palace.

“Upon arrival, we discovered this incredible national treasure,” he said, noting officials had “no record” of its origin.

Officials confirmed the gemstone was found during routine inspections of state property after the leadership transition.

Questions remain about prior administrations and whether the stone had been previously hidden or undocumented.

Mines Minister Calls Gemstone Collector’s Dream

Mines Minister Carl Andriamparany described the find as “an emerald with its natural matrix, extremely rare in Madagascar”.

“Officials have found no similar stone ever documented,” he said, emphasizing historical uniqueness.

Andriamparany added that gemstones in matrix, unlike cut stones, have significant scientific and collector value.

“If evaluated and managed properly, the state could benefit significantly from its sale,” he noted.

 Madagascar’s Mining Industry

Madagascar is a leading source of sapphires, rubies, and emeralds, exporting to global markets in Asia and Europe.

The country’s mining sector employs tens of thousands and contributes about 5% of GDP, according to government data.

Past discoveries, including the 73-carat ruby in 2017, generated millions in state revenue through controlled auctions.

Experts say transparency and proper valuation remain crucial for maximizing public benefit from gemstone sales.

Expert Analysis and Verification Pending

The gemstone requires professional evaluation to determine quality, size, and potential market value.

Mines Ministry officials confirmed international gemologists would be consulted for authentication.

Experts noted that emeralds in matrix are prized because the surrounding rock preserves natural formation.

The evaluation will establish legal eligibility for export and potential international auction standards.

Government Procedures and Transparency Measures

Colonel Randrianirina emphasized that the government would adhere strictly to national and international regulations during any sale.

“All steps will follow the law to protect the state’s interests,” he said.

Officials plan to document each stage, from appraisal to potential sale, and report to parliament for oversight.

Transparency is considered essential to prevent corruption and maintain investor confidence in Madagascar’s mineral sector.

International Interest in the National Treasure

The gemstone display attracted international media and collector attention, signaling potential market interest.

Industry specialists said emeralds in matrix are extremely rare, often sought for scientific study and museum exhibitions.

Some foreign institutions have expressed interest in inspecting the gemstone for research, subject to government approval.

Authorities confirmed that any foreign engagement would comply with Madagascar’s mining and export laws.

Security and Preservation Measures

Security around the Ambohitsorohitra State Palace was strengthened to protect the gemstone from theft or damage.

Preservation measures include controlled temperature and humidity to prevent deterioration of the matrix and embedded emerald.

Government officials stated that access is restricted until formal expert analysis is completed.

Additional security personnel will monitor the site continuously during the evaluation process.

Potential Revenue Implications for the State

The government sees the gemstone as a potential major source of revenue for the state treasury.

Mines Minister Andriamparany emphasized responsible management and legal compliance in handling the asset.

Similar gemstone sales have historically boosted Madagascar’s funds by millions, according to ministry records.

Officials highlighted that proper evaluation, documentation, and legal sale channels are essential to maximize economic benefit.

Historical Context of Gem Discoveries

Madagascar has a history of rare gemstone discoveries, including sapphires in Ilakaka and rubies in Vatomandry.

Previous finds have drawn international collectors and auction houses, enhancing the country’s profile in global gem markets.

Experts say such discoveries also raise questions about governance, transparency, and local economic distribution.

Authorities affirmed that lessons from past experiences would guide current management of the 300 kg gemstone.

Looking Ahead for Madagascar

The interim president’s administration faces scrutiny over governance and financial transparency.

Displaying the gemstone demonstrates national pride and a commitment to accountability.

Observers say proper management could improve public trust and attract investment in Madagascar’s mining sector.

Authorities reaffirmed that Madagascar will comply with all national laws and international standards regarding the gemstone.

“It might be sold, and it will be up to the minister,” Colonel Randrianirina said
