Diamond Rough to Polish in Surat, India
At Reeva Rare, every diamond begins its journey as a rough stone and transforms into a masterpiece of brilliance. The process of turning a rough diamond into a polished gem is a careful balance of science, precision, and artistry. Surat, India, is known worldwide as the diamond capital, and our artisans proudly continue that legacy through advanced technology and traditional craftsmanship.
Here’s how each diamond is transformed step by step.
1. Rough Diamond Selection and Grading
Every diamond starts as a natural rough crystal with its own shape, size, and clarity.
Our expert graders study each stone using advanced microscopes and 3D mapping software.
This helps identify inclusions, natural grain lines, and the best way to cut the diamond for maximum brilliance and value.
The goal during planning is simple — preserve carat weight, enhance beauty, and minimize waste.
Once the cutting plan is finalized, the diamond moves to the next stage for shaping.
2. Marking and Planning
In this stage, the rough diamond is marked with precise laser lines to guide the cutting process.
Using advanced computer models, our planners determine how to divide the stone to achieve the highest yield.
Each angle is analyzed to maintain balance between symmetry, sparkle, and value.
This stage ensures the diamond achieves its ideal cut — whether round, princess, emerald, or cushion.
3. Cleaving or Sawing
If the rough diamond has visible grain lines, it can be cleaved — split along these natural lines using a precise blade and gentle pressure.
For other stones, sawing is used instead. A high-speed laser or diamond-edged saw divides the rough into smaller, workable pieces.
Every cut is made with accuracy and care to protect the stone’s structure and prepare it for shaping.
4. Bruting or Shaping (Blocking)
Next comes bruting, also called blocking or shaping, where the diamond begins to take form.
Two diamonds are rotated against each other, or laser machines are used, to create the desired outline — round, oval, cushion, or any chosen shape.
This step also defines the girdle, the outer edge of the diamond.
Symmetry and proportion are critical at this stage, as they determine how light will reflect and create brilliance in the final gem.
5. Faceting and Polishing
Once shaping is complete, the diamond moves to the faceting and polishing stage.
Here, small flat surfaces called facets are carefully cut and polished on a rotating wheel coated with diamond powder.
This step reveals the diamond’s true sparkle, fire, and clarity.
Faceting is done in two parts:
Blocking: The first eight main facets are polished.
Brillianteering: Additional facets are added for symmetry and final shine.
This stage requires expert hands, patience, and precision — it’s where the diamond’s full brilliance comes to life.
6. Inspection and Grading
After polishing, each diamond undergoes a detailed quality inspection.
Experts check proportions, symmetry, and surface finish under magnification.
If minor adjustments are needed, they’re done carefully to achieve perfection.
The diamond is then graded for cut, color, clarity, and carat weight (the 4Cs) — ensuring it meets Reeva Rare’s premium standards.
7. Final Cleaning and Certification
Once the diamond passes all inspections, it’s cleaned using ultrasonic technology to remove every trace of residue.
Finally, the polished diamond is certified by trusted gemological laboratories such as IGI or GIA.
This certification guarantees authenticity, quality, and traceability before the diamond is ready for jewelry creation or export.
