- Other factors, such as the treatment and condition of the item, will result in a difference in evaluation.
- The market price list is based on the GIA's current grade.
- If the item's grade is unknown, we may ask you to leave the product with us temporarily to allow us to examine it accurately.
- Due to the influence of the gold and platinum market, prices may fluctuate even within the same day.
- The market selling price does not include handling fees. We will inform you about the handling fees at the time of the appraisal.

About Icons
The manufacturing and distribution process for brand products emits large amounts of carbon dioxide (CO2) and consumes large amounts of water. The images below represent the amounts of carbon dioxide and water consumption that can be reduced by reusing a product.
Carbon Dioxide (CO2) Reduction
CO2 reduction expressed by the amount of CO2 absorbed by a cedar tree annually.
Water Consumption Reduction
Water consumption reduction expressed by the volume of the 200-liter bathtub.
(Typical household bathtub size)
Our Calculation Method
-
The 'Resale Impact' is not a display of an actual environmental reduction but rather a quantification of the environmental impact (CO2 emissions and water consumption) generated by the manufacturing and distribution process that can be theoretically omitted when a customer purchases a product we resell instead of a buying a brand new item of the same type. Since our calculation is predicated on the emissions in the omitted manufacturing and distribution process, actual reductions in environmental impact may differ from our projected estimate.
-
Since our company does not manufacture goods, our calculations cover any resold goods (watches, bags, jewelry (including bullion), apparel, and accessories).
Our company does not check and verify the actual numerical value of each item's environmental impact (CO2 emission and water consumption) for our Resale Impact. Instead, we base our calculations on data from the LCA database "Gabi*" and estimate the total environmental impact of an item's entire life cycle, from the procurement of its materials to its disposal and/or recycling. Our calculations were overseen by a third-party consulting firm. -
Discrepancies in LCA results may occur due to differences in calculation assumptions or deficiencies in the manufacturing process.
-
Due to revisions in calculations, the latest calculated values of products may differ from those shown on product tags, etc.
**GaBi is a software provided by Sphera Solutions GmbH that evaluates the sustainability of products' lifecycles.
