Technical instructions for submitting jewellery projects: files, measurements, materials, quantities, finishes and feasibility criteria.
We cover the entire cycle: concept, modelling, prototype, casting, finishing. The client defines the goal — we handle the technical execution. Design, prototyping and manual finishing are done in‑house; casting and galvanic plating are entrusted to specialist partners in the Vicenza district, under our quality control. The client has a single point of contact and a single responsible.
Development of parametric and organic digital models in Rhinoceros and software CAD 3D. We accept industry-standard file formats: .3dm, .stl, .obj, .step. Mesh optimization for printing and casting.
High-resolution 3D resin printing for test prototypes. Validation of volumes, thicknesses, and tolerances before starting mold and series production.
Three-dimensional digital organic sculpting with controlled depth. Ideal for complex textures, portraits, logos, or floral patterns on curved or flat sterling silver 925 surfaces.
Lost-wax casting in certified sterling silver 925. Thermal cycle and alloy control to guarantee porosity-free castings. Contract manufacturing of micro-series and repeat production runs.
High-precision CNC milling and cutting on sterling silver 925 sheet with thicknesses from 0.5mm to 3mm. Clean geometries, sharp engravings, and perfect edges with no thermal deformation.
We manage protective and decorative galvanic baths (18k & 24k gold, rose gold, rhodium, ruthenium), clear cataphoresis, and e-coating through highly specialized, trusted galvanic partners.
Technical feasibility consulting during the creative design phase. Adaptation of external CAD files to guarantee proper metal flow, target weight compliance, and structural strength.
Effetti Preziosi combines the digital precision of CAD and 3D sculpting (software CAD 3D, Rhinoceros) with the tradition of lost-wax casting and CNC cutting on silver sheet. We do not limit ourselves to a single technique: we offer flexible and integrated solutions to bring complex collections, clean geometries or single prototyped pieces to life.

Real examples of projects and prototypes created internally with our technologies.
Development of very high-density meshes for a ring with complex floral and organic details. Automatic weight optimization for casting.
Modern geometric pendant with parallel grooves milled directly from a 925 sterling silver sheet without any thermal deformation.
Precision casting in 925 silver from a digital 3D sculpture. Sharp artistic micro-details and a polished-satin patina finish.
Linear process, direct communication. No bureaucracy: brief → model → prototype → production.
The client provides sketches, photo references or a project description. We assess technical feasibility, materials and timelines. Response within 48 business hours.
Digital model development in Rhinoceros and/or software CAD 3D. The client reviews and approves the file before proceeding. Revisions included in the phase.
Resin printing and proof casting in sterling silver 925. The prototype is shared with the client for final verification and approval before series production.
Series production based on the approved prototype. Finishing and polishing treatments. Rigorous quality control and delivery on agreed timelines.
