The creation

Gemma Bicolore is a two-tone engagement ring with diamond, crafted in 18-carat white and rose gold. The shank maintains a continuous and measured line, while the central section concentrates the character of the design: elements in the two colours of gold wrap around the stone with a symmetrical and fluid movement. The colour contrast makes the construction legible without weighing down the profile and accompanies the light of the diamond on the hand.

Design around the gemstone, don't adapt it afterwards

A traditional solitaire can become a personal project when every line is re-imagined around the gemstone, the hand, and the meaning to be treasured.

I'm handling the project directly to find the meeting point between aesthetic intention, construction and presence on the hand.

Personalised jewellery

Gemma Bicolore belongs to my archive and documents a journey born from a precise diamond, references chosen by the client and a custom-built solution. In my atelier in Altamura, a new creation does not start over from this same mounting: I consider the person, the proportions, the gems, the materials, the intended use and the meaning to be expressed, developing each time an independent structure that is consistent with the new project.

From inspiration to design

Inspiration

The client started from images of classic engagement rings, but wanted a setting with its own identity, particularly in the way it cradled the stone. I developed the setting by taking as a reference a flower that shares the name of the future bride, without turning it into a literal representation. The botanical suggestion thus enters the design through curves and coils, while the symmetry keeps the overall piece neat and contemporary.

Materials and finishes

I designed Gemma Bicolore in 18-carat white and rose gold around a natural diamond, adapting the structure to the proportions of the gemstone. 3D modelling and prototyping made it possible to check heights, thicknesses and presence on the finger before final production. This was followed by lost-wax casting, flush setting, polishing and quality control, with attention to the balance between the setting, the shank and wearability.

Certifications and registrations

Technical expertise, professional registrations and qualifications have accompanied the development of my work in the goldsmithing and jewellery field.

Awards and recognition

Since 2009, I have guided private clients and couples through the creation of their jewellery in my atelier. Over thirty years of goldsmithing experience guide every stage: listening, design, workshop, quality control, and delivery. Awards, mentions, and accolades tell the story of the artisanal, technical, and creative journey that underpins my work. Each badge links to an in-depth article on the blog.

How is a piece of jewellery born?

A piece of jewellery can be inspired by a specific request or by a story worth cherishing. It is Custom when it starts with a shape, a stone, a material or a style to be crafted to measure. It becomes narrative When transforming a memory, symbol or personal passage into substance, proportion and meaning. Wedding rings, rings, pendants, necklaces and bracelets can follow both paths. In the Jewellery section, you can discover which one best suits your idea.

Do you want to start from a creation like this?

Whether you start from a diamond, a shape you love, or a personal reference, I can design a setting capable of transforming these elements into a cohesive whole.

The initial meeting is to clarify desires, materials, structure, timelines, and feasibility. It doesn't require an immediate decision.
