What are they?

2D sketches and preliminary prototypes precede the manufacturing of the 3D jewellery models. Once the blueprints and preliminary prototype have been approved, the definitive 3D model starts to be elaborated.

They comprise:

  • dimensioned 2D blueprints, with top and side views and perspective.
  • Images that simulate the final appearance of the jewel with the gemstones set, known as render.
  • Estimate of the weight in metal
  • Estimate of the size and carats of the gemstones.

The blueprints, renders and estimates are obtained from a preliminary prototype in 3D. The preliminary prototype is a very simplified version of the final 3D model, and therefore it is cheaper. The client can optionally explore the prototype in detail with a 3D Visualizer, or obtain it in an STL file for 3D printing.


What is their purpose?

The preliminary prototype, renders and 2D blueprints provide a very similar resemblance to the final result.
They allow the customer to:

  • anticipate the aesthetic features of the final piece before its manufacture and to eventually request corrections.
  • Estimate the weight of the jewel and the carats of the gemstones.

Thus, expensive modifications in the final model or the risk of disappointment is minimised.

For a commission with several different design alternatives, a preliminary prototype, blueprint and render can be developed for each one of the alternatives, making it easier for the client to choose the most suitable.


What is the purpose of the preliminary prototype?

The preliminary prototype lacks the mechanical details (movements, clasps,...), of the aesthetic details (lace work or “ajour” for the gemstones). It can show inaccuracies regarding the width of the leaf. Therefore, it is not suitable for manufacturing.
