Science & craft
From personal material to a real diamond.
A complex laboratory process, explained clearly: preparation, controlled crystal growth, cutting and quality assessment.
The scientific sequence
Five stages. One genuine diamond.
The exact method and the role of personal material are confirmed after assessment. The written proposal explains the laboratory route for the individual commission.
- 01
Personal material
Maison reviews the source, suitability and handling requirements.
- 02
Carbon preparation
Accepted material is prepared for the agreed laboratory route.
- 03
Crystal growth
Carbon builds around a diamond seed under controlled conditions.
- 04
Cut & assessment
The crystal is cut, polished and evaluated as a finished diamond.
- 05
Diamond or jewel
The stone remains loose or becomes a made-to-order piece.
The difference
Same crystal. Different origin.
A laboratory-grown diamond has the crystal structure, hardness and optical properties of diamond. Its quality and clarity are assessed individually after growth and cutting.
Maison states the laboratory origin clearly and confirms the quality information and documentation available for the finished stone.
Origin & documentation
What looks alike can still be identified.
Origin is established through professional screening, specialised instruments and gemmological analysis—not by ordinary viewing.
Read practical questionsEssential questions
The science, answered plainly.
Yes. It is a genuine diamond crystal grown under controlled laboratory conditions. It is not glass, cubic zirconia, moissanite or another imitation.
The defining difference is origin. Natural diamonds form in the earth; laboratory-grown diamonds form through a controlled technological process. Both are diamond crystals.
You can share preferences. Maison explains which specifications can realistically be considered after the material and laboratory route have been reviewed.
Available documentation and reporting are confirmed in the proposal. Maison uses only language that can be supported for the individual project.
