Visit Gübelin Gem Lab ↗The short story
More than
a name.
A pearl may pass from maker to dealer, auction room or private collection while its story grows at every step. Gübelin Gem Lab offers a way to separate that story from what can be examined and reported. The useful first move is to confirm whether the laboratory’s current service covers the item and question in hand, then let the official report—not the sales narrative—carry the technical weight.
Why it is here
A useful starting point,
not a verdict.
Its official service information helps determine whether a particular pearl item and question fall within a laboratory report.

The researched view
Then, now and
what can be verified next.
This section follows the named sources. If a future direction is not published by the source, it is not added here.
A report sits inside a larger research system
Gübelin Gem Lab’s official service map places laboratory reports beside a reference collection, analysis and publications, age determination and provenance-focused research. The structure shows how item testing depends on accumulated comparative knowledge.
More than one document format
The current site lists gemmological reports, gemstone ratings, gem and jewellery passports, profiles and portraits, alongside laboratory-document verification and multiple order routes. These products have different purposes and should not be treated as interchangeable.
Provenance research is an active direction
The laboratory continues to publish research-and-development work including Provenance Proof and age determination. These are presented as research and service areas, not as a universal solution to every provenance claim.
Start by defining the document you need
The practical route is to compare the current document scopes, prices and ordering options, then verify any existing document through the laboratory’s own service before relying on it.
