FAQ
How does GemLens identify gems?
GemLens uses a photo of your gem, rock, or crystal. This image is sent to a third-party AI model for analysis, which then provides a possible name, species, or mineral group, along with reasons for the visual match.
What information does GemLens provide for free?
The free version offers a possible name and species or mineral group, model-reported observations about the photo, candidate-species reference properties, and reasons for the visual match.
What are the benefits of GemLens Premium?
Premium unlocks insights into factors affecting value, recommended appraisal steps, notes on treatments or imitations, and care guidance. It also provides a broader value range when a scale reference is present in the photo.
Can GemLens determine the geographic origin of a gem?
No, GemLens explicitly states that a photo cannot reliably determine geographic origin. It provides reference information only and does not promise accuracy regarding origin.
Is GemLens accurate for insurance or appraisal purposes?
GemLens is for reference information only and is not a laboratory identification, proof of authenticity, insurance valuation, price quote, or formal appraisal. Consult a qualified professional for such decisions.
How often is GemLens updated?
The app was last updated on September 29, 2026, with version 1.3.1. This indicates a recent update, suggesting ongoing development and support.
What devices does GemLens support?

Does GemLens have ads?
