Traders of precious stones across Tanzania are steadily delivering a range of minerals to the Tanzania Gemological Centre (TGC) ahead of the nation’s third gemstone auction, scheduled for Thursday, November 27, 2025, in Arusha.
The initiative ensures that all minerals intended for sale undergo thorough analysis and valuation before entering the auction.
This step not only promotes transparency but also strengthens the market value of Tanzanian gemstones, boosting investor confidence in the sector.
Officials anticipate that the auction will attract a strong turnout of local buyers, fostering healthy competition and expanding opportunities for traders.
The event is expected to play a key role in stimulating growth within Tanzania’s gemstone industry, which continues to contribute significantly to the country’s economic development.
