Catawiki always aims to offer you the best possible buying experience. Our experts virtually review and select every object in line with our submission guidelines. While we strive to provide a detailed description and photographs of each jewellery object, discrepancies or inaccuracies may occur. It is your responsibility to review all of the information provided about an object, including the condition and description, before placing an order. Sellers are responsible for the information, pictures and description provided, including the quality, quantity and nature of the jewelry supplied. A small imperfection that cannot be seen in the photo but is included in the description is not a non-conformity. A Lab Report is not a guarantee, valuation or appraisal regarding the articles described therein. A Lab Report contains only the characteristics of an article described after it has been graded, tested, examined, and analyzed using the techniques and equipment used at the time of the examination from that specific Lab. The results of any other examination performed on the article may differ depending when, how, by whom and with which grading standard the article is examined. In addition, any changes and improvements in techniques and equipment that may have occurred which may enable the examiner to detect, among other things, the use of processes for altering the characteristics of an article which use was previously undetectable, does not automatically mean the object does not conform to its description.
