Diamond Jewellery Manufacturing Process

Diamonds are the ultimate symbol of love, luxury, and elegance. At Kesh Gemstone, each piece is crafted with care, precision, and passion – from idea to masterpiece. Explore the complete step-by-step journey below:

1️⃣ DESIGN: Where Vision Meets Artistry 

Every masterpiece starts with an idea — a spark of creativity that blossoms into a timeless jewel. At Kesh Gemstone, our journey begins with design, where imagination transforms into reality.

Our skilled jewelry designers carefully sketch out each concept by hand or digitally, crafting the foundation of elegance and precision. These sketches are more than illustrations — they’re blueprints of emotion, style, and storytelling.

From the curve of a ring band to the delicate halo around a center stone, every detail is meticulously planned to bring harmony between beauty and structural strength.

📌 Purpose: Conceptualization & Visualization of the Jewelry Piece
📌 Tool Used: Fine Pencil, Precision Brush, Stylus & Digital Tablet
📌 Output: Hand-Drawn Artwork or Digital CAD Draft
📌 Design Types: Engagement Rings, Statement Earrings, Custom-Made Pendants, Signature Collections

💡 Did You Know?
Most Kesh Gemstone creations are born from client inspirations. Whether it's a vintage heirloom remake or a dream ring idea from a photo, our designers are experts in turning imagination into wearable brilliance.

2️⃣ CAD (Computer-Aided Designing): Precision in Every Pixel 

Once the hand-drawn sketch is perfected, it’s time to breathe digital life into the vision. At Kesh Gemstone, we use advanced CAD technology to turn artistic designs into accurate 3D blueprints — the engineering behind the elegance.

Using powerful software like Rhino, MatrixGold, or ZBrush, our skilled CAD artists build a 360° digital model of your jewelry. Every element — from the tiniest prong to the depth of the diamond seat — is measured with micron-level precision.

This step ensures perfect symmetry, durability, and stone fitting, while also allowing clients to preview the final structure before it’s crafted. The CAD design is the bridge between creativity and manufacturing.

📌 Purpose: Transform Sketch into 3D Digital Model
📌 Tool Used: Rhino, MatrixGold, JewelCAD, or Similar Software
📌 Output: 3D CAD Rendering (with Top, Side, and Perspective Views)
📌 Design Benefits: Precise Measurement, Structural Integrity, Realistic Visualization

💡 Kesh Tip:
Our CAD experts ensure every setting, curve, and metal thickness is perfectly calculated to hold your diamonds securely — guaranteeing both beauty and strength in your final jewel. 

3️⃣ RAPID PROTOTYPING: Bringing the Design to Life in Wax 

With the CAD model perfected, the next stage is to physically bring the design to life — this is where the magic of Rapid Prototyping begins. Using high-resolution 3D printers, we create an exact wax replica of the jewelry piece.

This wax model is a true-to-scale prototype, capturing every tiny groove, prong, and curve from the CAD file. It acts as a physical preview — the foundation used to build your final jewel in precious metal.

Our expert craftsmen inspect the wax model thoroughly to ensure dimensional accuracy, balance, and wearability before moving forward to casting. This process guarantees that every fine detail translates flawlessly from digital to reality.

📌 Purpose: Physical Prototype for Precision & Casting
📌 Tool Used: Resin-Based 3D Printers or Wax Carving Machines
📌 Output: Wax/Resin Model of the Jewelry Design
📌 Benefits: Accuracy, Cost-Efficient Testing, Structural Validation

💡 Did You Know?
Each wax model is custom-made for a single jewelry piece — ensuring true exclusivity. Once cast, the wax is melted away, making every mold one-of-a-kind, just like your jewelry. 

4️⃣ MODEL MAKING: The Birth of Form in Precious Metal 

After the wax model is perfected, we transition to the next transformative stage — Model Making, where your dream design takes shape in precious metal.

Using the lost-wax casting technique, the wax prototype is carefully encased in a heat-resistant plaster to create a mold. Once the mold is hardened, the wax is melted away, leaving a hollow cavity that captures every detail of the design.

Molten 925 sterling silver with 14K gold plating is then poured into the cavity, creating a raw metal version of your jewelry. After cooling, the casting is removed, and our artisans begin meticulously cleaning, refining, and checking every contour to ensure flawless structure and symmetry.

📌 Purpose: Convert Wax Prototype into Metal Form
📌 Technique Used: Lost-Wax Casting
📌 Metal Used: Solid 925 Sterling Silver with Premium 14K Gold Plating
📌 Output: Raw Jewelry Casting Ready for Stone Setting
📌 Benefits: Durable Structure, Detail Retention, Perfect Base for Gem Setting

💡 Craft Insight:
At Kesh Gemstone, we never compromise on purity or precision. Every casting is monitored for air bubbles, shrinkage, or imbalance — only the most perfect base continues to the next stage.

5️⃣ RUBBER MOULD MAKING: Preserving Perfection for Reproduction 

Before the final piece is assembled and adorned with diamonds, a crucial step ensures that its beauty can be replicated flawlessly — welcome to Rubber Mould Making.

Once the master metal model is approved, it is carefully encased in a block of high-quality vulcanized rubber. This rubber is cured under heat and pressure, forming a durable mould that captures every micro-detail of the design.

After cooling, the rubber is sliced open with precision to reveal a cavity that mirrors the original model. This mould allows us to inject hot wax repeatedly, producing identical wax copies for future castings — ideal for popular or custom repeat designs.

📌 Purpose: Create Reusable Mould for Consistent Reproduction
📌 Tool Used: Vulcanizing Press, Cutting Blades, Rubber Moulding Material
📌 Output: Flexible yet Precise Rubber Mould
📌 Benefits: Consistency, Efficiency, Perfect Replication of Original Design

💡 Kesh Standard:
We only use non-shrinking, premium rubber to ensure that every reproduction retains its sharpness and proportion — so each piece feels just as luxurious as the first. 

6️⃣ WAXING / WAX TREE: Multiplying Beauty in One Bloom 

Once the rubber mould is prepared, we move into the waxing phase, where multiple wax replicas are created from the mould — the beginning of batch production.

Each wax copy is injected with precision into the rubber mould using hot wax. These wax models are then carefully assembled onto a central wax stem, forming what we call a "Wax Tree" — a structure resembling the branches of a tree, with each branch representing a future jewelry piece.

This wax tree is vital for mass casting. It allows us to cast multiple pieces in a single operation, ensuring uniformity while maintaining high detail and craftsmanship in every piece.

📌 Purpose: Create Multiple Wax Copies for Batch Casting
📌 Tool Used: Wax Injector, Precision Tweezers, Wax Tree Assembling Kit
📌 Output: Fully Assembled Wax Tree Ready for Casting
📌 Benefits: Efficient Production, Uniform Quality, Time-Saving

💡 Artisan's Insight:
At Kesh Gemstone, each wax model is inspected before joining the tree. No imperfections are tolerated — ensuring that the final metal pieces emerge flawless from every branch. 

7️⃣ CASTING: From Wax to Precious Metal Brilliance 

Now comes one of the most magical transformations in jewelry making — Casting, where delicate wax forms become solid, radiant metal.

The assembled wax tree is placed inside a metal flask and surrounded by investment plaster to form a heat-resistant mold. Once the mold is cured, it’s heated in a furnace where all wax melts away, leaving a hollow cavity — a negative of every jewelry piece.

Into this cavity, molten 925 sterling silver with premium 14K gold plating is poured under extreme heat. As the metal fills every contour, it takes the exact shape of the original wax model. After cooling, the mold is broken to reveal a raw metal tree — the first glimpse of your soon-to-be stunning jewel.

📌 Purpose: Convert Wax Model into Precious Metal
📌 Technique Used: Lost-Wax Investment Casting
📌 Metal Used: 925 Sterling Silver with 14K Gold Plating
📌 Output: Raw Metal Jewelry Tree
📌 Benefits: Fine Detail Replication, Durable Base, Precision Craftsmanship

💡 Kesh Assurance:
Every cast is monitored for smooth flow, metal purity, and integrity. Our expert casters ensure zero porosity and perfect form, so your jewelry is not just beautiful — it's built to last.

8️⃣ GRINDING: Refining the Foundation of Brilliance 

After casting, the raw jewelry emerges from the mold in its roughest form — full of potential, yet requiring expert hands to refine it into a flawless beauty. This is where Grinding (also known as Filing & Assembly) begins.

Our master artisans cut each piece from the metal tree and begin carefully filing away extra metal, casting lines, and sprue marks. Using ultra-fine tools, rotary grinders, and files, they smooth the surface, define the edges, and prepare every curve for a perfect finish.

If the design has multiple parts (like a ring head and band), they are now assembled and laser-soldered together with incredible precision. This ensures the piece is structurally sound and beautifully balanced before moving to stone setting.

📌 Purpose: Smooth & Shape Raw Casted Jewelry
📌 Tools Used: Files, Rotary Grinders, Micro-Motors, Laser Soldering Tools
📌 Output: Fully Assembled, Smooth Jewelry Base
📌 Benefits: Clean Finish, Structural Alignment, Ready for Stone Setting

💡 Kesh Craftsmanship:
This stage demands absolute focus. A single uneven stroke could compromise the symmetry. That’s why each piece is refined under high magnification — because true beauty is born in the details.

9️⃣ FILING & ASSEMBLY: Shaping the Soul of the Jewel 

With the raw casting complete, our next mission is to perfect every curve, corner, and contour. This stage — Filing & Assembly — is where raw metal transforms into a refined masterpiece, ready to be adorned with diamonds.

Our expert artisans begin by carefully removing the sprues (metal channels from casting) and any uneven surfaces left behind. Using precision files, abrasive wheels, and micro-motor tools, they smooth every edge and sharpen each detail — ensuring flawless symmetry and comfort.

For designs with multiple components (like multi-band rings, double-head settings, or hidden halos), this is the moment they are assembled and fused together. Laser soldering or micro-welding ensures perfect structural integrity without compromising aesthetics.

📌 Purpose: Smooth, Refine & Assemble the Jewelry Base

Even the underside of a ring or the hidden gallery of a pendant receives the same attention as its front. Because at Kesh Gemstone, luxury is in every detail, even the ones you don’t see.

🔟 PRE-POLISHING: Revealing the Inner Shine Before the Sparkle 

Before the diamonds touch the metal, the surface must be prepared to mirror their brilliance — that’s where Pre-Polishing comes in.

After filing and assembly, each jewelry piece is carefully buffed and polished to smooth out microscopic scratches, tool marks, and uneven textures. Using soft brushes, felt wheels, and fine abrasives, our artisans create a silky finish that ensures light reflects smoothly once the gemstones are set.

This step is crucial — it not only enhances the visual appeal of the metal but also prevents debris or rough spots from interfering with delicate stone settings. It’s the calm before the sparkle — the silent shine beneath the brilliance.

📌 Purpose: Smooth & Prepare Surface Before Stone Setting
📌 Tools Used: Polishing Motor, Buffing Wheels, Rouge Compound, Ultrasonic Cleaner
📌 Output: Semi-Finished, Lustrous Jewelry Base
📌 Benefits: Clean Surface, Enhanced Metal Shine, Perfect Stone Seating

💡 Kesh Precision:
Even though this polish is temporary and refined again later, it is treated with the same level of detail as the final finish — because excellence begins from within. 

1️⃣1️⃣ STONE SETTING: Placing the Heart of Every Creation 

Now comes the moment where metal meets magic — Stone Setting, the soul of your diamond jewelry. This is where each natural HPHT earth-mined diamond is meticulously placed into its reserved seat, bringing the entire design to life.

At Kesh Gemstone, our master setters work with extreme precision under microscopes, ensuring each stone is aligned, secure, and perfectly angled to reflect light brilliantly. Whether it’s a solitaire, halo, pavé, prong, bezel, or invisible setting, every style is handled with personalized expertise.

The claws are gently folded, tension is calibrated, and each stone is checked for symmetry and security — because we believe diamonds deserve nothing less than perfection.

1️⃣3️⃣ RHODIUM PLATING: The Armor of Brilliance & Elegance 

To ensure lasting beauty, tarnish resistance, and a crisp, luminous finish, each silver-based jewelry piece at Kesh Gemstone is treated with a final layer of Rhodium Plating — a signature of true luxury.

Rhodium, a rare and precious metal from the platinum family, is electroplated over our 925 sterling silver with 14K gold plating to enhance shine, increase durability, and protect the metal from oxidation or dullness over time.

The piece is first ultrasonically cleaned to remove all residues. Then, it is submerged in a specialized rhodium bath, where a thin, bright-white layer is deposited using low-voltage electric current. This results in a smooth, scratch-resistant, and allergy-safe finish.

📌 Purpose: Enhance Shine, Protect Against Tarnish & Scratches
