Open the page of a high-value lot, and the image and the estimate naturally come first. What determines whether the lot deserves a closer look, however, is a different set of information: its provenance, condition, certificates and accompanying items. Each answers a different question, and each has limits to what it can prove. This guide follows the order we use in our own documentation work, and closes with how to request further material.

Provenance: where it comes from — not proof of authenticity on its own

Provenance records an object's history of ownership and transfer. It may draw on the consignor's account of how the piece was held, on past purchase records, or on public traces such as exhibition and publication history. The more specific a provenance entry is, and the more of it can be cross-checked, the clearer the direction for further verification.

Provenance is not, however, an authentication conclusion. A complete-looking ownership narrative does not replace examining the object and its documents. Conversely, an object with a brief provenance record is not necessarily problematic — it simply means understanding needs to be built in other ways.

Condition: a starting point for checking, not a final conclusion

A condition description answers the question ‘what state is it in now’. When reading one, note which parts are described, whether signs of wear, servicing, repair or restoration are mentioned, and whether the description covers the whole piece or only part of it. Any independent laboratory or grading report should be reviewed separately according to the subject and scope stated in the report itself.

However detailed, a written description is not the same as a first-hand inspection. For important pieces, the more reliable approach is to book a viewing and examine the key areas in person or by video — or to ask a specialist you trust to look on your behalf.

The value of a condition description is that it tells you what to check — it does not do the checking for you.

Certificates and documents: the issuing body first, then the subject and the scope

Certificate material is often summarised in a single line, yet three things deserve separate attention. First, the issuing body: which organisation produced the report, and how widely it is recognised in its field. Second, the subject: whether the report covers the principal stone, the entire piece, or only part of it — a gemmological report on a centre stone does not, by itself, cover the metalwork. Third, the scope and the date: what the report states, what it does not, and when it was issued.

The absence of a certificate does not mean there is a problem, and the presence of one does not mean every question is answered. The more useful questions are: which documents currently exist for this lot, what does each of them cover, and what is still missing. Reading documentation with these three questions in mind is far more reliable than simply asking whether a certificate exists.

Reviewing a lot's certificate alongside object details
Certificates and documents should be reviewed together with the object itself.

Accompanying items and supporting documents: check what is actually included

Accompanying items and supporting documents may include original boxes, warranty cards, booklets or purchase receipts for jewellery and watches; and dust bags, boxes, brand cards, warranty cards or other materials for handbags, where actually available. A more complete set of documents and accessories makes later review and transfer easier, but does not by itself establish the condition of the object. Each item should still be checked, including whether card dates correspond to the piece and whether accessories are original. A careful lot listing states what is actually included rather than relying on a general note such as ‘full set’.

When you would like to know more about a lot

If the provenance, condition, certificates or accompanying items of a lot leave you wanting further material, you are welcome to ask us directly: request the detailed images and document descriptions currently available; book a viewing to examine the key areas in person or by video; or raise the specific questions you care about, which we will help confirm with the consignor.
