At Colonial Gemstones , our story is one of passion, precision, and authenticity. For generations, Colombia has been celebrated as the birthplace of some of the world’s most coveted green gems — stones that embody beauty, history, and craftsmanship.
Our journey is led by Mauro Carvajal , an expert whose lifelong fascination with emeralds began during his travels through the legendary mining regions of Muzo, Chivor, and Coscuez. Inspired by the rich heritage and natural splendor of these mines, Mauro dedicated himself to mastering the art of sourcing, cutting, and evaluating emeralds.
With years of experience working alongside miners, gemologists, and designers, Mauro developed an unparalleled understanding of what makes each stone unique. Driven by a vision to bring transparency, quality, and integrity to the global market, he founded Colonial Gemstones — a bridge connecting the heart of Colombia’s emerald legacy to the world.
Every stone we offer is hand-selected, certified, and sourced with care. Whether you’re designing a custom engagement ring, building a fine jewellery collection, or investing in a timeless piece, we believe in more than just selling gemstones — we believe in sharing stories.
With Mauro’s expertise and our unwavering commitment to excellence, Colonial Gemstones offers not just emeralds, but a legacy waiting to be worn.
Mauro doesn’t just work behind the scenes! He’s taken Colonial Gemstones on the road, showcasing his incredible finds at the hottest international exhibitions.
