Step 1: Plan the Cut – Maximize Brilliance and Value

Before cutting, expert diamond cutters analyze the rough stone to determine the best approach. Proper planning ensures the diamond retains the most carat weight while achieving maximum brilliance.

🔹 Scan & Map the Rough Diamond: Advanced laser technology detects inclusions and determines the optimal cut.
🔹 Maximize the Yield: Cutters balance weight retention with brilliance to create the most valuable gem.
🔹 Choose the Best Cut: The diamond’s natural shape influences whether it becomes a round brilliant, princess, or another fancy cut.

Once planned, the cutting process begins. Mistakes can’t be undone, so every decision matters.

Step 2: Cleave or Saw – Divide the Diamond

After planning, the cutter separates the rough stone into smaller sections using one of these methods:

• Cleaving: The cutter strikes the diamond along its natural growth lines to split it into pieces.
• Laser Sawing: High-powered lasers precisely cut through the diamond, minimizing waste and maximizing accuracy.

This step shapes the diamond for the next stage of refinement.

Step 3: Shape the Diamond – Bruting the Edges

At this stage, the cutter shapes the diamond into its final form. Traditionally, cutters bruted diamonds by spinning two stones against each other to round their edges. Today, laser technology allows for faster, more precise shaping.

Step 4: Add Facets – Create the Sparkle

Faceting unlocks a diamond’s brilliance by strategically placing tiny, light-reflecting surfaces. The process happens in two stages:

• Blocking: The cutter adds the first 16–18 facets to establish the diamond’s basic shape.
• Brillianteering: The cutter refines the stone by adding additional facets, enhancing fire, brilliance, and scintillation.

Proper faceting ensures the diamond reflects and refracts light beautifully, creating the dazzling sparkle people love.

Step 5: Polish the Diamond – Achieve a Flawless Finish

After faceting, the cutter polishes each facet to perfection. Using a spinning wheel coated with diamond dust, the cutter removes any microscopic scratches. This process enhances the diamond’s brilliance and smoothness, making it ready for final inspection.

Step 6: Inspect and Grade the Diamond

A polished diamond must pass a strict quality check before reaching the market. Experts evaluate:

✔ Cut Quality: How well the proportions reflect light.
✔ Symmetry: The precise alignment of facets.
✔ Polish: The smoothness and clarity of the surface.

After passing inspection, the diamond goes to a gemological laboratory like GIA or IGI for official certification.
