What certification from Amorim Fine Violins is

Certification answers the first question anyone asks of a fine instrument: what is it. Who made it, where, and when. The conclusion is a certificate of authenticity signed by Amorim Fine Violins: a professional opinion we stand behind, and one that stays with the instrument for the rest of its life. We certify antique instruments only. Every certificate is issued together with its dossier: the research, the analysis and the condition report that led to the conclusion. We do not issue one without the other.

When a certification is needed

Selling or consigning

Buyers, dealers and auction houses ask who made it before they ask anything else. A certificate with its dossier answers that question in full.

Insurance & appraisal

Value rests entirely on attribution. Certification is the step that makes any figure meaningful.

Inheritance & discovery

An instrument surfaces in a family, or comes with a name attached and nothing to support it. Certification establishes what is actually there.

A second opinion

An existing certificate you want tested. We review attributions issued by others, and tell you plainly whether they hold up.

how we do

How we establish an attribution

01

Examination by hand

Scroll, f-holes, arching, varnish, purfling and internal construction, read against documented examples of the attributed maker's work. This is where an experienced eye does what no instrument can do for it.

02

Analysis in the Amorim Lab

Imaging and dating that reach past the surface: what lies beneath the varnish, what has been repaired, when the wood was felled and where it grew.

03

Provenance research

The instrument's documented history, past owners, auction records, existing certificates, literature. A verifiable chain of ownership is one of the strongest supports an attribution can have.

04

Comparison, and the conclusion

The instrument measured against known reference instruments of the period: proportions, model, working habits, materials. Where the evidence holds, the certificate is signed and the dossier assembled.

Luiz Amorim, Violin Expert

Decades spent reproducing the great Italian makers.

That study is also where his expertise comes from. Reproducing an instrument means measuring and accounting for every choice its maker made, the arching, the thicknesses, the varnish, the marks of the tools. Over decades, work of that kind builds an eye that identifies a maker's hand and understands its detail. It is why the same person who creates the atelier's new instruments also signs its Certificates of Authenticity.

The dossier and the Amorim Lab

A certificate tells you who made it. A dossier tells you what it truly is today.

Every certificate we issue comes with its dossier printed and digital. It is the whole case, set out so that anyone examining the instrument in ten or fifty years can follow the reasoning: the maker's history, a full description of the instrument, its provenance, the Amorim Lab analysis with its imaging plates, and a condition report.

The Amorim Lab

Diagnostic Techniques

The Amorim Lab combines complementary diagnostic methods according to each instrument and the questions that need to be answered. These techniques allow us to study materials, construction, condition, restoration history, and attribution with greater depth, always forming part of a broader expert assessment.

01

UV Light Fluorescence

UV light helps reveal restorations, varnish layers, surface repairs, and later interventions that may not be visible under normal light. It also supports comparison between original varnish characteristics and altered areas.

02

Infrared Imaging

Infrared imaging allows us to look beneath the varnish, revealing wood grain orientation, construction details, tool marks, and hidden issues such as cracks, woodworm damage, or open seams.

03

X-Ray Imaging

X-ray imaging examines the internal structure of the instrument without invasive intervention. It can reveal past repairs, reinforcements, internal construction, and details of the maker's working method.

04

Dendrochronology

Dendrochronology analyses the tree-ring patterns of the spruce top to help establish the age and origin of the wood, adding important evidence to attribution and historical context.

05

Comparative Analysis

Comparative analysis places the instrument alongside known reference works by related makers, schools, and periods, studying design, proportion, craftsmanship, and construction choices.

06

Integrated Assessment

No single technique is conclusive on its own. Each instrument receives an individual assessment, where technical findings are combined with expert judgment to form a complete and coherent picture.

Certification or appraisal

Which one do you need?

The two are often confused. They answer different questions, and most owners eventually need both — in this order.

Certification: what the instrument is A signed attribution establishing maker, place and period, issued with its full dossier. Permanent: it stays with the instrument and is read by every future owner, dealer and auction house. The foundation. Nothing can be valued until it is known.

Appraisal: what the instrument is worth A signed statement of value, prepared for a defined purpose and valid as of a stated date. Built on the attribution, the condition and current market evidence. Dated by nature. Required by insurers, estate lawyers and serious buyers.
