Description from the seller
Solitaire ring in 18 kt white gold with Old European Cut natural diamond of 1.10 ct
A piece of jewelry with timeless charm, where the tradition of fine jewelry meets the essential elegance of 18 kt white gold.
At the center of this refined creation is set a significant natural diamond of 1.10 carats, characterized by the evocative Old European Cut. A historic cut, recognizable for its proportions and the special play of light, which gives the stone a unique identity and charm different from contemporary brilliant cuts.
The mount in 18 kt white gold enhances the presence of the diamond, making it the absolute protagonist of the composition. The clean lines and the prongs complete an elegant design, capable of crossing eras without losing its refinement.
