Suitable items
Gemstones Submission Guidelines

At Catawiki we want to ensure that the items in our auctions reflect the unique, harder to find objects of value that bidders are looking for.

This is why we have set per category a minimum estimated value a lot should achieve in auction in order to be admitted.

During lot evaluation our in-house Experts carefully review and select admittable items, considering various aspects and product characteristics that determine the quality and influence the value an item is expected to sell for in our auctions. 

 

At Catawiki we auction gemstones gathered from all corners of the world.

For our auctions we seek and select:

- a wide range of natural gemstones and gemstones with selected standard treatments (or without treatments).

- gemstones that are in a good condition and that have a sufficient quality in cut and clarity to be mounted in jewellery.

- gemstones that are accompanied by a trusted gemological certificate.

- gemstones that have a minimum estimated lot value of €100 (as single stones, or, for selected gemstones offered as parcel).


If you need any extra guidance regarding our acceptance criteria, please find the submission guidelines attached below.
