OUR JOURNEY
Three Generations.
An Enduring Passion.
Our journey began in 1940, when Mr. Mohammad Suleman established his diamond cutting and polishing workshop. His son, Mr. Usman Ali, continued the craft and devoted approximately two decades to teaching students from India and overseas, becoming Head of the Diamond Department at the Gemstone Artisan Training School.
Today, Mr. Salman Ali carries this knowledge into the third generation, with specialised expertise in natural fancy colour diamonds.
Explore Our JourneyA personal passion
Pink, in all its
extraordinary nuances.
Pink diamonds hold a special place in Mr. Salman Ali’s work. From individual stones to calibrated melee, matching pairs and complete halo sets, we help you explore the subtle differences that make each selection personal.
Tell us your preferred shade, shape and size. We will discuss current options, photographs, videos and any available laboratory reports with you.
