The soul of this engagement ring
At the heart of this bespoke creation signed by the J. Bonneville workshop beats a gem of absolute purity. This pre-owned engagement ring reveals a natural brilliant-cut diamond of 0.63 carat displaying G colour and VS2 clarity. Its ideal dimensions of 5.43 by 5.47 by 3.44 millimetres maximise the reflection of light with a crystalline visual rendering. The 950 platinum embraces the stone with infinite grace, creating a captivating asymmetrical dynamic. The Meilleur Ouvrier de France artisan forged a pre-owned jewel whose timeless allure transcends the ages. Reference 820-06-2024 illustrates the genesis of this exclusive commission where the noble density of the metal meets the delicacy of an organic design.
Architecture and jewellery expertise
The ring body adopts a crossed profile enveloping the central motif in a remarkably fluid movement. Technical mastery is expressed through the setting of the main diamond, held in suspension by claws extended from the very shoulder of the mount. This architectural choice frees the pavilion of the stone and floods the collet with constant brilliance. The band is adorned with a pavé of brilliant-cut diamonds displaying F-G colour and VS clarity. Each secondary gem is fixed by a grain setting of absolute regularity, highlighting the curves of the alloy with surgical precision.
