Gemstone Journey

A lifelong passion for rare and beautiful stones

About Me

With over 15 years in the gemstone industry, I've dedicated my life to sourcing the world's finest colored stones. My journey began in the gem markets of Sri Lanka, Bangkok, Chanthaburi, Cambodia, Vietnam, Laos where I developed an eye for quality and authenticity.

Specializing in sapphires from Sri Lanka , I've built relationships with miners and cutters across three continents to bring exceptional gems to collectors and jewelers.

Each stone in my collection is hand-selected for its exceptional color, clarity, and character - representing nature's most beautiful creations.
