The Real Value

Beyond Just Measurement

DimBox is designed to solve the three biggest bottlenecks on the factory floor.

Unwavering Consistency

Get the exact same measurement on every stone, every time, regardless of which operator is running the machine. ±10 micron repeatability guarantees standardisation.

De-skill The Shop Floor

Stop depending on one or two expert graders. Any operator can run DimBox with minimal training, freeing up your skilled workforce for higher-value tasks.

Local Audit Trail

Every stone measured is automatically logged to an Excel file on your machine. Keep a permanent, transparent record for packing lists and customer audits.

Operator Workflow

As Simple As 1-2-3-4

A foolproof, automated loop that anyone can master in minutes.

2
Width
Horizontal size of the diamond from left to right
3

3
Ratio
Length to width ratio (defines elongation)

Cushion Cut

A square or slightly rectangular shape with soft rounded corners — like a cushion. Dimbox checks size, proportions, and that all four corners curve equally.

What Dimbox Checks
1
Length
Horizontal size of the diamond from left to right
2
Width
Vertical size of the diamond from top to bottom
3
Ratio
Length to width ratio (defines square or rectangular profile)
4
All Sides
Checks the symmetry of all four side lengths (S1, S2, S3, S4)
Width Length S1 S2 S3 S4 A1 A2 A3 A4
Princess Cut

A perfectly square diamond with sharp, crisp corners. Dimbox checks that all four corners are exactly 90° and none of them are chipped or uneven.

What Dimbox Checks
1
Length
Horizontal size of the diamond from left to right
2
Width
Vertical size of the diamond from top to bottom
3
Ratio
Length to width ratio (perfect square is 1.00)
4
All Sides
Checks the symmetry of all four side lengths (S1, S2, S3, S4)
5
All Angles
Measures all four corner angles (A1, A2, A3, A4) to ensure exact 90° corners
Width Length S1 S2 S3 S4 A1 A2 A3 A4
Emerald Cut

A rectangular shape with clipped (cut-off) corners. Dimbox measures the clipped corners at two different angles and checks they are all consistent.

What Dimbox Checks
1
Length
Horizontal size of the diamond from left to right
2
Width
Vertical size of the diamond from top to bottom
3
Ratio
Length to width ratio (defines elongation)
4
All Sides
Checks the symmetry of all four side lengths (S1, S2, S3, S4)
5
All Angles
Measures all four corner angles (A1, A2, A3, A4) for consistent clipped corner cuts
Width Length S1 S2 S3 S4 A1 A2 A3 A4
Baguette

A long, narrow rectangular stone with straight sides. Dimbox ensures the width is perfectly consistent from top to bottom and all four corners are sharp 90° angles.

What Dimbox Checks
1
Length
Horizontal size of the diamond from left to right
2
Width
Vertical size of the diamond from top to bottom
3
Ratio
Length to width ratio (defines elongation)
4

Length L Max W Min W S1 S2 S3 S4 A1 A2 A3 A4
Tapered Baguette

A variation of the baguette where one end is intentionally wider than the other. Dimbox measures both ends precisely to determine the exact degree of tapering.

What Dimbox Checks

Max W
Width of the wider end
2
Min W
Width of the narrower end
