AI Diamond Analyzer From a Photo
Upload one clear image and turn visible diamond details into an organized, plain-language report for preliminary research.
Photo-based, AI-assisted
What a CaratScanner report covers
Likely stone indicators, apparent shape, an approximate size and carat range, visible color, clarity and cut observations, and broad USD market-value context.
What the AI diamond analyzer reviews
CaratScanner studies features that can be observed in the submitted image and organizes them into a practical report. It is designed to help buyers, sellers, collectors, and jewelry owners understand which questions to ask next—not to replace physical testing.
Because the workflow begins with a photograph, every output is expressed as a likely indicator, visible observation, approximate range, or broad market context. That wording matters: a camera can reveal appearance, but it cannot measure chemistry or exact weight.
- Likely indicators associated with natural diamonds, lab-grown diamonds, moissanite, zircon, and similar stones
- Apparent round, oval, princess, cushion, emerald, pear, radiant, marquise, heart, and related shapes
- Approximate visual size and carat-weight range rather than an exact scale measurement
- Visible color, clarity, cut, proportion, symmetry, polish, and condition cues
- Broad estimated USD market-value context based on the apparent characteristics
- A structured report that can be reviewed before laboratory testing or an appraisal
How to photograph a diamond for analysis
Clean the stone gently, place it against a simple background, and use soft, even light. Keep the camera steady and make sure the stone is in focus. The outline and center of the stone should remain visible without being covered by fingers, labels, or interface graphics.
A face-up image is useful for shape, facet pattern, and visible clarity cues. If the stone is mounted, prongs and reflections may hide important details. Avoid digital zoom, beauty filters, screenshots of compressed listings, and colored lighting because they can change apparent color and edge definition.
How to use the report responsibly
Use the report to compare visible characteristics, prepare questions for a jeweler, or decide whether further testing is worthwhile. A mismatch between a seller's description and the photo-based observations is a reason to investigate, not proof that either source is wrong.
For an expensive purchase, resale, insurance schedule, or authenticity decision, compare the stone with its grading document and arrange an in-person examination. Exact carat weight requires a scale or reliable measurements, and origin claims require suitable gemological instruments.
Frequently asked questions
Can AI identify a diamond from one photo?
AI can compare visible cues with patterns associated with diamonds and common look-alikes, but one photo cannot prove a stone's composition or origin. Treat the result as preliminary guidance and use laboratory testing when certainty matters.
What diamond details can CaratScanner review?
A report can organize likely stone-type indicators, apparent shape, an approximate size and carat range, color direction, visible clarity and cut observations, condition cues, and a broad estimated USD market-value range.
What kind of photo gives the clearest result?
Use a sharp, close image with the entire stone visible, even lighting, minimal glare, and a simple background. Heavy reflections, blur, filters, unusual angles, and hidden settings reduce the information available for analysis.
Is the result a diamond certificate or appraisal?
No. A CaratScanner report is an automated visual estimate. It is not a laboratory certificate, guarantee of authenticity, insurance valuation, or professional appraisal.
