The 4-prong solitaire: a natural balance
The 4-prong setting does not try to impress.
It stands on its own, through balance.
Four points of contact, nothing more.
The diamond is held securely, yet never confined. Light moves freely, the stone breathes, and everything becomes clear.
It is a quiet form.
You don’t notice the setting, you see the diamond.
A diamond selection that allows precision
Here, the choice goes beyond standard options.
It becomes intentional.
This solitaire is offered with carefully selected GIA certified diamonds, each chosen for its balance and presence:
-
0.50 ct H SI
-
0.50 ct F VS1
-
1.00 ct H SI1
-
1.00 ct F VS1
-
1.00 ct E VVS1
-
1.50 ct H SI1
-
1.50 ct F VS1
-
1.50 ct D IF
Each combination reflects a different direction — subtle, expressive, or uncompromising.
The right choice is not the most perfect.
It is the one that feels right.
A setting that disappears with precision
The setting is not meant to stand out.
It holds.
The prongs are shaped to secure the diamond without adding weight.
The open gallery allows light to pass through without obstruction.
The inner band is gently rounded, ensuring comfort throughout the day.
Everything is in place. Nothing is excessive.
Crafted in Lausanne, without shortcuts
Each ring is made to order in our Lausanne workshop.
This approach requires time, attention, and consistency.
The diamond is selected first.
The setting follows.
Never the other way around.
This model is often chosen for a simple reason: it does not try to convince.
It is self-evident.

Is the diamond always GIA certified?
Yes. Each diamond is delivered with its original GIA certificate.
How should I choose between the different qualities?
H SI offers a well-balanced combination of brilliance and value.
Higher grades such as F VS1, E VVS1 or D IF provide increased whiteness and clarity.
The difference is not only visible.
It is perceptible.
What is the difference between 0.50 ct, 1.00 ct and 1.50 ct?
0.50 ct remains refined and discreet.
1.00 ct offers a stronger presence.
1.50 ct creates a more assertive visual impact.
Is the ring comfortable for everyday wear?
Yes. The band is designed for comfort and the setting minimizes snagging.
What are the production times?
On average 10 to 15 business days.
Can I see the ring or the diamonds before purchasing?
Yes. We offer private appointments in Lausanne or video consultations with our gemologist.
