ELONGATED
Cushion & Radiant
Consider length-to-width ratio, corner character and the balance between brilliance and outline.
CUSTOM-CUT LAB-GROWN DIAMONDS
A Diamond Cut Around Your Vision
Commission a lab-grown diamond with the shape, proportions and visual character considered for your intended design—not simply selected from standard inventory.
BEYOND A STANDARD SHAPE
Cut With Intention
A custom cut begins with a clear brief: shape, outline, ratio, target size, colour, clarity and the piece it will eventually become. We guide those decisions, explain the practical trade-offs and define the specification before sourcing or cutting begins.
THE POSSIBILITIES
Shape, Ratio and Colour
From refined classics to distinctive elongated and fancy silhouettes, the brief is shaped around your aesthetic and design requirements.
SCULPTURAL
Marquise & Pear
Directional shapes require careful symmetry, point protection and proportions suited to the setting.
PERSONAL
Heart & Fancy Shapes
A distinctive outline can be refined through lobe shape, cleft, symmetry and overall spread.
COLOUR
Fancy-Coloured Lab Diamonds
Pink and other colour directions are considered alongside tone, saturation, cut and availability.
CLASSIC
Oval & Emerald Cut
Familiar shapes become individual through ratio, facet pattern, corner treatment and visual spread.
THE SPECIFICATION
Defined Before It Is Cut
01
The Visual Brief
We define the desired outline, ratio, target dimensions, colour direction and intended use.
02
Proportion and Performance
Spread, depth, symmetry and facet architecture are considered together. One priority can affect another, so the trade-offs are made clear.
03
Review and Documentation
The finished stone is reviewed against the agreed direction. Applicable independent laboratory documentation is provided or discussed according to the commission.
HOW IT WORKS
A Clear Custom-Cut Process
Each stage is confirmed before the next begins.
Share the Brief
Tell us the shape, size, colour, timing, intended jewellery design and investment range.
Confirm the Direction
We clarify feasibility, specifications, trade-offs, estimated timeline and next steps.
Cut and Review
The diamond is produced or sourced to the agreed direction and reviewed on completion.
Create the Piece
The stone can then be integrated into a bespoke SARATTI ring or jewellery design.
FROM STONE TO JEWEL
Designed as One Composition
The strongest result comes when the diamond and setting are considered together. We can develop the final ring or jewellery piece around the stone’s exact measurements, outline and character.
CUSTOM-CUT QUESTIONS
The Details, Made Clear
Final specifications, tolerances, timing and documentation are confirmed individually before a commission proceeds.
What is a custom-cut lab-grown diamond?
It is a lab-grown diamond produced or finished to an agreed shape and proportion brief rather than selected only from readily available standard inventory.
Can I request any shape?
Many classic and fancy shapes can be considered, but feasibility depends on the requested outline, proportions, size, colour direction and available starting material.
Can I specify the exact carat weight?
A target range is usually more practical than an exact final weight. Cutting decisions, proportions and material removal affect the finished carat weight.
Can I choose the length-to-width ratio?
Yes. Ratio is a key part of the brief for elongated shapes, within reasonable production tolerances.
Are fancy-coloured lab-grown diamonds available?
They may be available depending on colour, intensity, size, shape and current production possibilities. The requested direction is assessed before confirmation.
Will the diamond be certified?
Applicable independent laboratory documentation is discussed as part of the specification. The laboratory and report format depend on the finished diamond and commission.
How long does a custom cut take?
Timing varies according to the brief, production route, approvals and documentation. An estimate is provided once feasibility has been reviewed.
Can SARATTI design the finished ring?
Yes. The diamond can be integrated into a bespoke engagement ring or other jewellery design developed around its final measurements.
Can the process be completed remotely?
Yes. Suitable commissions can be guided through private digital consultation, written specifications, imagery and design reviews.
What happens if the final result differs from the target?
Natural production tolerances and cutting outcomes are explained before confirmation. The review process and applicable next steps depend on the agreed brief and commission terms.
