This is the license that comes with every 3D file and cutting file we sell: the same terms
as the LICENCE.txt inside each download. It is published here so you can read it before you buy.
Also available as plain text.
In short. Personal, non-commercial use: render it, print it, cast it, cut a stone for yourself or as a gift. No selling what you make with it, no sharing the files. Business use needs a commercial license, so ask us. The figures and data we publish are a different matter: they are free for everyone under CC BY 4.0.
1. The licence
You buy a licence, not the files. When your payment is confirmed, Compliance Condo B.V. grants you a personal, non-exclusive, non-transferable, worldwide and perpetual licence to use the files in this product on the terms below. Your licence key, shown on your order page and in your receipt, identifies this licence, so please keep it. All rights not granted here are reserved.
2. Who may use the files
The licence belongs to the person who bought it, for their own private, non-commercial use. It does not extend to a business, an employer, a client or anyone else. Everyone who uses the files needs their own licence.
3. You may
- open, view, render and animate the files for your own personal projects;
- 3D print or cast the model, and cut stones from the cutting file, for yourself or as a gift, as long as no money or other payment changes hands;
- modify and convert the files for these personal uses;
- post images and renders you made with the files on your own non-commercial social media or hobby forums, with a credit to Digital Gemology.
4. You may not
- use the files, or anything made with them, commercially: selling or offering for sale, commissioned or client work, advertising, or any use in or for a business;
- sell stones cut from the cutting file, or objects printed, cast or otherwise made from the model;
- share, sell, give away, lend, upload or sublicense the files, or any modified, converted or re-exported version of them, on their own or as part of anything else;
- include a file, or geometry derived from it, in another file product, pack, library, template, plug-in, game asset, NFT or marketplace listing;
- use the files to train, test or build any system that generates or reproduces geometry, including machine-learning models;
- remove the copyright notice or metadata that identifies the files as ours, or claim authorship of the cut designs.
5. Commercial use
Selling stones or jewelry, working for clients or using the files in a business needs a commercial licence. Write to support@digitalgemology.com and we will help.
6. Names inside the files
Some files carry another trading name of Compliance Condo B.V. That name, like Digital Gemology, is not a separate company, so this licence covers those files too. Where a file refers to LICENCE.txt, it means this licence.
7. Using the files
A cutting file describes geometry exactly. How a real stone turns out also depends on the rough, the material, the machine, the index gear, the laps and the skill of the cutter. Make a trial cut in inexpensive material before you cut valuable rough. A 3D model describes the stone's shape; settings, seats and tolerances remain your design decisions. Measured figures describe the modelled geometry. They are not a grading report, certificate, appraisal or valuation of any stone.
8. If you breach this licence
If you seriously breach this licence, it ends and you must delete the files.
9. Your rights
Our terms and conditions apply to the files, except that this licence replaces the file licence in Article 9 of those terms. If a file is missing, corrupt or does not match its description, tell us and we will repair or replace it. Nothing in this licence limits your statutory rights as a consumer.
10. Law
Dutch law applies to this licence. If you are a consumer living in another country, you keep the protection of the mandatory law of that country.
