Some things are worth knowing exactly.

Where a piece was made. Who made it. Whose hands it passed through before it reached yours. These are old questions — as old as the objects themselves. What's new is what we can do with them.

Papillon Pearl Labs sits at the convergence of the ancient and the cutting edge — where the discipline of historical research meets the rigor of artificial intelligence, and where the story of an object is treated with the same seriousness as any other form of evidence.

This is a research practice. Not a brokerage. Not an auction house. Not an authentication service. Research first. Everything else follows from that.

The convergence of the ancient and the cutting edge.

Three Ways In

one—

the tool

Search recipes, hallmark reference, T1/T2/T3 confidence framework, and a structured authentication decision tree. Free. 1 analysis without an account.

two—

the library

Two volumes, four rapid-response papers, and one peer-reviewable methodology — published openly under CC BY 4.0. Read the work before you engage the practice.

three—

consultation

Three engagement tiers covering quick attribution review, full dossier preparation, and heir outreach work. Disclosure terms per Vol II §8.4.

Research, then service. In that order.

The Library is the foundation. Every consultation engagement applies methodology developed openly in the published corpus, with attribution confidence stated in plain terms — Tier 1 documented, Tier 2 attributed, Tier 3 speculative.

The separation matters. Research is the public record. Consultation is its application. Both are anchored to the same evidentiary standards — the same Four-Field Audit, the same T1/T2/T3 confidence framework, the same discipline of naming what is known and what isn't.

A Note on the Practice

This is not a brokerage, an auction house, or an authentication service.

Papillon Pearl Labs is a research practice. We publish what we learn, and we consult on application of the methodology. We do not sell pieces, we do not certify, and we do not appraise for insurance. For institutional engagements that require formal certification, see the methodology page for our scope of work.
