## What is Diamond Grader?

Know what you're looking at.

Diamond Grader turns the camera in your pocket into a jeweller's loupe. Photograph a diamond and advanced AI vision examines what your images genuinely show — then tells you, plainly, what they cannot.

THE CAPTURE STUDIO
A guided camera built for stones. Frame the diamond inside the loupe and get live coaching on light, focus, reflections and framing. The face-up shot is the only one needed. Crown, profile, detail, certificate and UV are optional, and each one raises confidence.

YOUR ASSESSMENT
• The 4Cs — apparent colour range, clarity range, cut characteristics and carat
• Ranges rather than false precision, with a confidence level on every finding
• Visible inclusions and blemishes, each labelled by how certain it really is
• AI Loupe — zoom deep into your photograph, with findings marked where they were seen
• Symmetry, proportions, polish and fluorescence indications
• Market insights, given as ranges, in your currency
• Buying insights: strengths, concerns, and the questions worth asking a seller
• Selling insights: how to describe a stone honestly and position it well
• Compare against a grading report you already hold
• A shareable report, and your full history kept on your device

HONEST BY DESIGN
Photographs have limits, and this app says so. Where the evidence isn't there you get "insufficient evidence" rather than a guess. A weight you supply is never overwritten by an estimate. Nothing is ever presented as a certified grade.

WHAT THIS IS NOT
This is an AI visual assessment of photographs. It is not a laboratory grading report and it is not an appraisal. It cannot determine whether a stone is natural, laboratory-grown, a simulant, or treated — no photograph can. It does not replace physical examination, or a report from an accredited gemmological laboratory. Diamond Grader is not affiliated with, or endorsed by, any gemmological laboratory.

LEARN
Free, always: the 4Cs, diamond shapes, understanding inclusions, natural versus laboratory-grown, fluorescence, certificates, pricing, buying safely, and how to photograph a diamond well.

PRIVACY
Photographs you choose to assess are sent over an encrypted connection to an AI provider for processing. You are asked to consent before this happens for the first time, and you can withdraw that consent at any time in Settings. Your photographs, reports and notes are stored on your device.
