BADEN PORTACIO PROFESSIONAL GEMOLOGY
Welcome to a BP Emerald:γ
Professional Gemologist Β· Specialist in Colombian Emeralds
Passionate about gemstones from an early age, I trained as a professional gemologist with a special focus on Colombian emeralds, dedicating my career to the study, certification, and promotion of high-value, authentic gems.
My experience ranges from laboratory gemological evaluation to consulting in acquisitions, investment, and the curation of private collections.
Currently, I develop projects focused on cultural outreach, ethical trade, and the enhancement of the patrimonial value of Colombian emeralds in the international market, with a special emphasis on Asia.
My work is guided by three core principles:
πΉ Scientific rigor
πΉ Commercial transparency
πΉ Respect for the origin and history of every gem
I am based in Nagoya, Japan, where I promote partnerships between the Latin American gemological world and the Asian public through federations, educational workshops, cultural events, and professional certification initiatives.

We are proudly Colombian, our emeralds are of high quality from the beautiful South American country. Colombia has the unique geological conditions for the formation of emeralds of exceptional quality.
Unlike other deposits around the world, Colombian emeralds form in hydrothermal deposits associated with shale and calcite, which influences their purity and color.
Distinguishing Characteristics
- Color: Intense and pure green, with no predominance of excessive yellow or blue.
- Transparency: Greater clarity compared to emeralds from other countries.
- Inclusions: They exhibit natural “gardens” that are a mark of authenticity, often visible under magnification.
