Services & Restoration

Our Commitment.


Litinvs’s commitment to customer service is an indispensable element of its activities. This includes our pledge to service, repair, or restore in-house any Litinvs portrait engraved jewel regardless of its age. We want to provide service at the highest possible level.

This ambition is one of the fundamental criteria of the Litinvs Seal.

Authentication

In The Historical Archives.

Whether your portrait jewel eventually needs to be overhauled, repaired, or restored, e
very portrait cameo entrusted to Litinvs for servicing or repair is first checked against the manufacture’s historical archives.

These “archive books” are part of the legacy of Litinvs in which every cameo crafted since 1839 is recorded. The serial number of each cameo submitted is noted so that its life cycle can be traced.


Steps Of Servicing

The Litinvs Service Procedure.

As a rule, Litinvs requires one to two hours to disassemble a simple portrait cameo with approx. 12 or more components (included complications) in a clean, dust-free glass environment.  Problems, if any, must be identified during this phase. As soon as the individual parts have been disassembled, they are cleaned to remove microscopically small particles and performed into the glass environtment.

Case and chain are only polished, (portrait gemstone not need re-polishing, only incase of damage). Polishing may involve gentle retouching or several interventions that require differentiated techniques:
  • Traditional polishing is performed manually and requires a “free-hand” technique, relying on extensive experience, virtuosity, and quick reflexes.
  • Alternative techniques include satin finishing, lasering, and diamond polishing that results in a mirror gloss.
  • It is important to note that there is a limit to the number (30 times) of polishing sequences that can be applied during the lifetime of a cameo case.
  • A final inspection is performed when the case-related interventions are completed. The integrity of water resistant is checked.
  • Then, the main gemstone portrait is mounted into the case and finally, is cased up. After the last traces of moisture have been removed, the case is sealed. This is followed by a rate test and an overall inspection.

  • In this phase, the portrait cameo jewel is subject to an inspection that focuses on both technical benchmarks and aesthetic aspects. The final inspection can last up to 12 hours.
The assembly of the parts must be performed in a sequence that is precisely defined for each model and includes many separate steps such as isolation/clearness specific components. Adjustments & fittings of the case are made during and after assembly to assure flawless functionality as well as rate accuracy according to specifications.

Restoration

The Replicate Procedure.

We maintain an inventory of artwork with several parts and case components from past eras as well as a collection of original tools. In the event that cameo jewel is partly broken required parts, we will replicate them with the original tools and ancestral know-how.

FRONT BORDER ADJUSTMENT REPLICATE PROCESS WITH RESPECT TO THE INDIVIDUAL CAMEO DNA.

To keep these traditional techniques alive, we pursue an ongoing policy thanks to which ancestral skills are passed on to the younger Litinvs generation who work in this restoration department. Portrait Jewel must have preserved its original value and historic integrity and must function in the same manner as when it was manufactured. The decisive aspect is that Litinvs restorate is aware of the impact of their interventions with respect to the individual DNA of each portrait cameo jewel.
