Specialists in Brazilian precious gemstones since 2010
A passion that became a legacy
Porto Gemas was born from a passion for Brazilian precious gemstones — a unique natural heritage that Brazil offers to the world. Founded in Minas Gerais, the heart of national mining, our company specialized in selecting, certifying, and trading the highest quality gems.
Every stone that passes through our hands is evaluated by certified gemologists, ensuring unparalleled authenticity, provenance, and quality. We work directly with trusted miners and lapidaries, eliminating intermediaries and offering the best price to the end customer.
Our mission is to connect you to the geological wonders of Brazil — imperial topazes from Ouro Preto, Paraíba tourmalines and much more — with the safety and credibility you deserve.
