Diamonds are admired for their beauty, strength, and brilliance—but what truly makes them extraordinary is the journey they undergo before reaching perfection.
The diamond manufacturing process is a precise combination of technology, craftsmanship, and experience, transforming rough stones into dazzling gems.
At Shree Diamond Mfg, every diamond is crafted with accuracy, care, and international quality standards
What Is Diamond Manufacturing?
Diamond manufacturing is the process of converting rough diamonds into polished, market-ready gemstones. This process involves several stages, including planning, cutting, polishing, quality control, and certification.
Each step plays a crucial role in enhancing the diamond’s sparkle, symmetry, and value.
Step-by-Step Diamond Manufacturing Process
1. Selection of Rough Diamonds
The journey begins with the careful selection of rough diamonds.
Key factors evaluated:
-
Shape and size of the rough stone
-
Natural inclusions and flaws
-
Color potential
-
Yield estimation (how much polished diamond can be recovered)
Expert gemologists at Shree Diamond Mfg analyze each rough diamond to determine the best possible cut and value optimization.

2. Planning & Mapping (Diamond Analysis)
Before cutting begins, advanced technology is used to map the internal structure of the diamond.
Tools used:
-
3D scanning
-
Laser mapping technology
-
Computer-aided design (CAD)
This stage ensures:
-
Maximum brilliance
-
Minimum weight loss
-
Ideal symmetry
Planning is one of the most important stages because a single wrong decision can reduce a diamond’s value significantly.
3. Diamond Cleaving or Sawing
Once the plan is finalized, the rough diamond is divided.
Two main techniques:
-
Cleaving: Splitting the diamond along its natural grain
-
Sawing: Using laser or diamond-coated blades for precise cuts
At Shree Diamond Mfg, modern laser technology is used for accuracy and safety, ensuring clean and controlled separation.
4. Diamond Cutting (Shaping)
After sawing, the diamond is shaped into its desired form.
Popular diamond shapes:
-
Round
-
Princess
-
Emerald
-
Cushion
-
Oval
This stage defines the foundation of the diamond’s beauty.

5. Diamond Polishing
Polishing is where the diamond truly comes to life.
Using high-precision polishing wheels, artisans carefully polish each facet to achieve:
-
Maximum sparkle
-
Smooth surfaces
-
Perfect angles
This step requires exceptional skill and patience, as even minor errors can affect brilliance.
6. Quality Control & Inspection
Every polished diamond undergoes strict quality checks.
Inspection includes:
-
Cut precision
-
Symmetry and proportions
-
Surface finish
-
Optical performance
Only diamonds that meet international quality benchmarks move forward.
7. Diamond Certification
Certified diamonds provide transparency and trust.
Independent gemological laboratories evaluate diamonds based on the 4Cs:
-
Cut
-
Color
-
Clarity
-
Carat
Certification ensures authenticity and market acceptance.
8. Sorting & Grading
After certification, diamonds are sorted based on:
-
Size
-
Shape
-
Quality
-
Client requirements
This step is crucial for bulk orders, exports, and custom jewelry manufacturing.
9. Packaging & Export Preparation
The final step is secure packaging and export readiness.
At Shree Diamond Mfg, diamonds are:
-
Safely packaged
-
Labeled accurately
-
Prepared according to international export standards
This ensures safe global delivery and customer satisfaction.
