More information before selling or buying
See what each service examines, what it costs and what appears on the listing or in your personal report. A review provides additional information and points of attention, but is never an unlimited guarantee of authenticity, value or a risk-free purchase.

Differences and costs
Estimate and Expert valuation are added to a listing by the seller. An interested buyer requests the buyer review before purchase and receives a personal report.
For the seller
A ONEJWL Expert determines a reference value. The listing shows a value range 10% below and above that value, without an extensive report card or personal expert presentation.
€5.00 excl. VAT
€6.05 incl. 21% VAT
For the seller
An expert value range under the ONEJWL system. The value and the reviewing expert’s name are published with the listing. This seller service does not include a personal buyer report card.
€10.00 excl. VAT
€12.10 incl. 21% VAT
For the buyer
A personal digital review before purchase. After payment, the expert examines the listing, seller, photos and available documents and provides a report within 24 hours with findings, risks, unknowns and limitations.
€39.00 excl. VAT
€47.19 incl. 21% VAT
Important: additional information, not a guarantee
A digital review is based on what the expert can examine through the listing, photos, questions and documents. It does not guarantee authenticity, a fixed sale value, a faultless seller or a risk-free purchase. If material, stone treatment or authenticity can only be established physically or in a laboratory, the report states this as a limitation or unknown.
Personal buyer report
The expert records not only conclusions, but also the sources used, uncertainties and what cannot responsibly be established digitally.
View report explanationHow to request a review
The review applies to one specific item. If you do not yet have a listing, create one first with clear product information.
Upload sharp photos, hallmarks, dimensions, weight and any certificates. The expert may request additional information.
You see the price and scope in advance. A buyer review starts after payment; a seller valuation is charged once when the item sells through ONEJWL.
ONEJWL assigns the request to an expert in the appropriate field. Progress and any questions are tracked.
You receive a summary of findings and, for a valuation, a substantiated value estimate within the agreed scope.
The result describes the review performed and the information that was available. Without physical inspection or laboratory testing, it is not an unlimited guarantee of authenticity. ONEJWL therefore always shows which form of examination was used.
