Surat, India · Est. 2003 · Diamond Atelier
Natural round diamonds cut and polished by master artisans — over two decades of precision trusted by the world's foremost diamond houses.
The Koladiya Legacy
In 2003, Sureshbhai and Dalapatbhai Koladiya founded Dwarkesh Diamond with a single conviction: that every natural diamond deserves to be finished with absolute precision — regardless of scale. Not as policy. As promise.
Rooted in Surat — the city that cuts ninety percent of the world's rough diamonds — our expertise is concentrated entirely on natural round brilliants. Twenty-three years later, over 2.5 million stones carry that conviction into the world's finest jewellery.
"We do not polish diamonds. We reveal what nature created. That distinction is everything."
— Sureshbhai Koladiya, Founder
Three Disciplines
We are specialists in one discipline — the round brilliant cut. This singular focus is our greatest strength.
Sixty years of collective knowledge guide every cut. Crown angles held to 34–35°. Pavilion at 40–41°. Forty-seven crown facets placed with tolerances measured in microns.
Three sequential polishing stages. Each surface brought to optical glass clarity. No cutting marks. No surface aberrations. Only light.
Before any stone leaves our floor, it is measured for brilliance, fire, and scintillation against GIA-grade benchmarks. If it does not pass, it returns.
The Journey
A disciplined engineering process transforms rough diamonds into perfectly symmetrical round brilliance. Every angle, every facet — crafted with purpose.
Expert assessment of rough diamond clarity, colour, shape potential, and structural integrity. We evaluate feasibility for round cut geometry, projected yield, and optimal weight retention before any work begins.
Technical 3D planning defines optimal table size, crown angle (34–35°), pavilion angle (40–41°), and girdle thickness. Every proportion is engineered for maximum light return and GIA-grade symmetry.
Precision execution of facet cuts using calibrated cutting wheels. Maintaining exact symmetry and alignment across all 57 facets — the foundation of superior round brilliant optical performance.
"The difference between a good diamond and a great diamond is not found in the rough. It is found in the hands that finish it."
High-precision diamond wheel polishing removes all cutting marks and creates mirror-smooth facet surfaces. Sequential polishing stages on crown, girdle, and pavilion optimise light reflection and surface grade.
Rigorous validation of symmetry, polish grade, facet alignment, and light performance. We measure brilliance, fire, and scintillation to GIA standards before any stone is approved for delivery.
