Four Prongs for One Carat

In round brilliant cut, a 1 carat diamond reaches an average diameter of about 6.5 mm. At this dimension, the 4-prong setting reveals its purpose: metal becomes scarce around a stone that no longer needs underlining. The setting holds, light circulates, and the diamond occupies the space that belongs to it.

The Benchmark Carat

One carat has long been the weight against which others are measured. Neither a contained promise nor a demonstration: a point of balance. On this pared-down setting, that weight finds a direct expression, readable at a glance, with nothing to amplify or restrain it.

The Amplitude of a Mastered Presence

A one carat diamond asserts a different presence. Not through excess, but through amplitude. Its strength lies less in demonstration than in a right proportion between volume, light and balance. On this setting, that presence appears naturally. It is often the choice of those seeking a more assertive presence, faithful to the same precision.

Three Readings of the Diamond

Three qualities are offered for this model, each accompanied by its GIA report. As the stone grows, its color and its purity become more legible: this is why this carat opens one more option.


H SI1, Natural Brilliance. The balance between presence and light, an essential beauty, ample and luminous.


F VS1, Refined Light. A further expression of whiteness and purity, for the finesse and depth of its light.


E VVS1, High Purity. An exceptional whiteness, paired with purity of exception.

Three degrees of rarity. Three readings of the same solitaire.

Choosing Your Precious Metal

White gold 750, yellow gold 750, rose gold 750 or platinum 950. White gold and platinum merge into the stone's light and extend its reach; yellow and rose gold frame it with a contrast the diamond's amplitude carries without losing itself.

The Time of Adjustment

In Lausanne, each ring is made to order. The more the stone gains in amplitude, the more decisive the adjustment of the setting becomes: the four prongs are taken up one by one on the chosen diamond, then the ring is checked before delivery.
