Gem Mining & Buying Rough in Madagascar
Our artisanal gem mining and buying center is located in the mountain region of Madagascar. We focus on purchasing, identifying, and pre-faceting rough gemstones directly from local miners, supporting their communities.
Madagascar is known for its wide range of gemstones, including sapphires, rubies, and tourmalines. Our center works closely with miners who rely on artisanal methods to extract these stones. This partnership provides sustainable income to families and helps protect the environment through responsible mining practices. When buying, we place great emphasis on quality. Our gemologists identify and evaluate each stone by its color, clarity, and size. We examine microscopic inclusions on-site in our laboratory, as these features reveal the gem’s origin and authenticity. Understanding these inclusions gives each stone its own story and deeper significance.
Once the rough gems are identified, we move to the pre-faceting stage. This process carefully prepares each stone for cutting and polishing to maximize brilliance. Our lapidaries shape every gem with precision, bringing out its natural color and pattern. The result is a finely prepared rough, ready for the next stage of craftsmanship.
The Madagascar Mining & Buying Center combines local artistry with modern expertise. Every purchase supports sustainable mining and helps preserve Madagascar’s unique gemstone heritage.
Buying Rough & Cut Emerald in Colombia
Our Buying Center in Bogota, Colombia, specializes in sourcing top-quality emeralds from the legendary Muzo Mine. Muzo is known for producing the most coveted emeralds in the world, valued for their deep green color with a natural blue cast and exceptional inner life.
Evaluating a Muzo emerald goes far beyond lab metrics. We study how light moves through each crystal, how its internal structure breathes, and how natural inclusions confirm origin and integrity. Every stone carries its own signature, and recognizing that takes years of field experience rather than textbook grading.
Working directly with miners and trusted local partners gives us early access to fine material before it reaches brokers. Every deal is done face to face, built on transparency and respect for the community. Our focus is on authenticity, not marketing language. Buyers are welcome to explore our Colombian emeralds or request custom sourcing through GemstonePortfolio.com.
