That would mean nothing if the geometry came out of a model that guesses. So the most useful thing this notice can tell you is where artificial intelligence is *not* involved, and then be straight about where it is. ## No geometry and no measurement is generated by AI **Every 3D model, every cutting file and every measured figure we sell or publish is built by deterministic geometry and physics.** Facets are constructed from stated angles and indices, the models are exported from that construction, and light is traced through the result according to the optics of the material. There is no neural network, no training data, and nothing learned from other people's designs. The practical consequence is reproducibility. Load one of our GemCad files into your own software and you will find the same angles we published. Trace the same cut, at the same refractive index, under the same protocol, and you get the same numbers today, next year and on your machine rather than ours. If you ever find a figure or an angle from us that you cannot reproduce from the file and the stated method, treat it as an error and tell us. ## Where we do use AI We are a small company, and like most small companies we use general-purpose AI tools as assistants. Being specific about that is more useful than a vague reassurance. **Written copy** Drafting and editing assistance for product descriptions and articles. A person decides what is published and is answerable for it. **Marketing imagery** Some campaign visuals may be AI-generated or AI-assisted. These are labeled. See the rule below on product previews. **Internal work** Research, code assistance and document drafting, including parts of these notices. What AI is never used for: - **Producing, adjusting, smoothing or estimating any facet, angle, file or published measurement.** - Making any decision about a person: who we sell to, at what price, or on what terms. - Answering you while pretending to be a human being. ## How we label what AI makes The EU AI Act requires people to be told when content is artificially generated. We think the honest version of that rule goes a little further than the letter of it, so: - **A product preview always shows the file you are buying.** Previews are renders of the actual geometry in the download, never a generated impression of it. - Renders are labeled as renders. They are computed images of a modeled stone, which is neither photography nor AI. - AI-generated or AI-assisted imagery is labeled as such where it could otherwise be mistaken for a photograph or a render. - We publish no synthetic imagery or audio of a real person. - If we ever put a chatbot on the site, it will say it is a machine on first contact. ## Our position under the AI Act Regulation (EU) 2024/1689 sorts AI systems by risk. Ours is the simple end of it. **Prohibited practices** We operate none of them. No social scoring, no emotion recognition, no biometric categorization, no untargeted scraping of faces, no manipulation of vulnerable people. **High-risk systems** None. We do not use AI to make decisions about people, and none of the purposes we use it for is on the Act's list of high-risk areas. **Transparency obligations** These apply to us as a user of generative tools, and are what the labeling rules above are for. **General-purpose AI models** We build none. We use third-party tools as a customer. We are a **deployer** of AI, not a provider of it. We are not required to register anything, and we make sure that whoever uses these tools here understands what they can and cannot do, because a tool used without understanding is where the harm actually comes from. ## A person is always accountable Nothing reaches you because software produced it. Every file, sentence and figure passes a human who is answerable for it, and "the model wrote it" is not an excuse we will ever offer you. If something we published is wrong, it is wrong because we published it. ## Your files, your data and AI We do not put customer personal data into public AI tools, and we do not use your data, or anything you make with our files, to train models, ours or anyone else's. How we handle personal data generally is in the [privacy policy](https://digitalgemology.com/privacy). ## Telling us we got it wrong If you believe something we published was AI-generated and not labeled, or that a figure cannot be reproduced, write to [support@digitalgemology.com](mailto:support@digitalgemology.com). We would rather correct it than defend it. ## What is changing The AI Act arrives in stages. The prohibitions on unacceptable practices have applied since February 2025, the rules for general-purpose AI models since August 2025, and the transparency rules and the enforcement regime from **2 August 2026**. Obligations for high-risk systems follow on **2 December 2027**. Nothing we operate falls into the high-risk tier, and we will update this notice if that changes. This notice describes our own practice and is published for transparency. It is not legal advice.
