Our diamonds
Origin & Standards
Natural or laboratory-grown, every diamond is chosen for its balance and its harmony with the setting. GIA certificates for natural stones, IGI for laboratory-grown.
IGI · The wonder of science
Laboratory-grown diamond
The same chemical, physical and optical structure as its natural counterpart, without mining.
- The same fire, the same clarity, 100% diamond
- No mining
- A larger stone for the same budget
- The 4Cs
- Carat, colour, clarity and cut: the four criteria that govern the light in a stone, and its price.
- Our selection
- We keep only the stones whose proportions serve the setting — balance matters more than the carat figure alone.
“Laboratory-grown diamonds have essentially the same chemical composition, crystal structure, optical, and physical properties of diamonds found in nature. Differences only become clear when they are viewed by a trained grader in a gem laboratory.”
Our craft
Accuracy & Precision
Every creation takes shape from a bespoke model, then passes to our workshop to be formed, set and checked to an exacting standard.
- 01
The Inspiration
A private meeting to understand what you have in mind and to select the centre stone.
- 02
The Design
The model: your choices become a 3D mock-up accurate to the millimetre, approved with you before anything is made.
- 03
The Making
The hand: casting the gold, shaping, setting under a binocular microscope — every gesture is carried out in our workshop.
- 04
The Inspection
Proportions, security of the stones, polish: nothing leaves the workshop without a full check.
- 05
The Delivery
An exceptional case and a certificate of authenticity accompany your creation.
Frequently asked questions
What to know before choosing
None, physically, chemically or optically — the GIA confirms it. The difference is origin and rarity: one formed inside the Earth, the other was grown. At equal budget, a laboratory-grown diamond buys a larger stone.
