Craftsmanship is at the heart of our company. The hands of our craftsmen masterfully combine skillful creativity, experience and talent, achieved after long years of training dedicated to learning the specific goldsmithing techniques that represent NANIS DNA and make our jewels so distinctive.
Our artisans engrave the surface of precious metals by hand etching deep cuts with a burin tool.
This surface finishing permits light to penetrate and illuminate the gold, radiating a warm
glow across each piece.
The burin consists of a rounded handle shaped like a mushroom, and a tempered steel shaft, coming from the handle at
an angle, and ending in a very sharp cutting face.
Burins typically have a square or lozenge shape face, though
several other types are used.
The golden surfaces of NANIS jewellery are always perfectly finished. Obtaining these magical surfaces takes skilful and delicate hands. Hands that can perfectly control the finger pressure to polish with light and precise touches the tiny surfaces of our precious jewellery.
This is a delicate operation, made by skillful, delicate hands, achieved by the uses of 20 different brushes and seven different types of abrasive pastes in order to reach the best finishing results.
This procedure requires extreme attention to avoid any modification to the original shape of the jewel.
All our jewels are hand-finished. Smoothing, engraving, polishing and all other types of finishes are performed patiently by our craftspeople’s hands.
Every process brings with it different challenges. Differences due to the shape of the jewels. Difficulties increased by the presence of edges, moulding, soft spirals or perfectly level surfaces, by inaccessible crevices and by particularly delicate elements…
This is where it sometimes becomes impossible to brush polish, as commonly occurs, pieces with hidden and apparently unreachable corners.
Therefore, we turned to the centuries-old tradition of the trade, recovering the ancient method of thread polishing.
A simple and effective method of polishing otherwise inaccessible concavities. An elementary process that consists of repeatedly sliding a cotton thread forwards and backwards in the cavity to be polished, applying slight pressure until achieving the desired result.
A slow and precise process, the repetition of a simple gesture like a drop of water smoothing the cliff face.
