How much is an emerald from Minas worth? Color, cuts and report define the price
According to O Antagonista, color, transparency, weight and the work of the cutter separate a rough stone from a high-value gem.

An emerald can leave the mine worth little and, after being cut, reach much higher prices. According to O Antagonista, a simple rough emerald from Minas Gerais costs around R$50, while the same cut gem costs R$60,000 per carat.
The text explains that the starting price in mining depends on the weight, the saturation of the green and the impurities. The final value, however, is defined by other factors, such as color, transparency and the work of the cutter, who decides how to use the stone.
Color accounts for around 40% of the final grade, according to the publication. Vivid and deep green tones are more valued than light or yellowish tones. The green comes from chromium and vanadium present in beryl, the mineral that forms emerald.
Classic pricing considers four criteria: color, cut, clarity and carat weight. According to the text, a stone with few internal cracks is rare. The internal marks that experts call gardening help distinguish natural from synthetic gemstones.
The rough from Campos Verdes or Itabira loses mass during cutting, as the cracks are cut. The price per carat varies depending on the quality and finish, but the text does not mention values for these ranges. Buying raw requires a trained eye, as there is a risk of hidden cracks.
Minas Gerais is presented in the text as an international reference in mineral extraction, and its gems reach jewelry stores in Europe and the United States, according to the publication. The safest path for the buyer, the text indicates, is the cut piece accompanied by a gemology laboratory report. The document certifies the origin and facilitates resale.
What changes for the investor
The report deals with gemstones, and not assets traded on the stock exchange, so it does not contain data that allows measuring the effect on prices. Still, there is a useful parallel for those who invest: value depends on verifiable information, and a provenance document reduces the distance between what the seller knows and what the buyer can verify. This analysis is not a recommendation to buy or sell and does not project prices.
