A digital model of the jewellery is created with a 3D printer, which builds up the model with a special type of wax.
A casting compound is prepared and poured into a cuvette (a steel cylinder), into which the wax model is placed.
Once the compound in the cuvette has dried, it is placed into an oven heated to 750o , melting the wax model.
The precious metal is melted and pressed into the cuvette, filling the space left by the wax.
The cuvette is plunged into cold water …
… and then the casting compound is carefully crumbled away, freeing the raw piece of jewellery.
After the oxide residue is removed, the jewellery is separated from its ‘tree’ and polished.
The jeweller drills space for the gemstone and secures it into place.
21Diamonds uses only the highest quality diamonds from a carefully selected provenance.
Finally, the jewellery is polished by hand to a fine finish.
