A free diamond appraisal app can triage your item: likely jewelry type, visible metal marks, setting style, certificate presence, condition issues, and whether the piece should move to professional appraisal. It should not promise exact carat weight, color, clarity, treatment status, or lab grade from photos alone.
Diamond screening checklist
- Certificate: photograph GIA, AGS, IGI, HRD, or other lab reports if present.
- Stone view: send clear top, side, and profile photos in natural light.
- Setting and marks: photograph metal marks, maker marks, serial numbers, and designer stamps.
- Condition: show chips, abrasions, loose prongs, missing side stones, repairs, resizing, and wear.
- Measurements: include ring size, item dimensions, and any known carat weight.
- Context: include boxes, receipts, old appraisals, insurance schedules, and family notes.
What the free screen can and cannot do
It can help decide whether your item looks like costume, fashion, estate, designer, lab-certified, or potentially higher-value diamond jewelry. It cannot replace lab grading, diamond testing, physical inspection, or a signed appraisal for insurance or sale.
When to get a professional appraisal
Use professional appraisal for engagement rings, diamond earrings, estate diamond jewelry, colored diamonds, designer pieces, insurance, resale, donation, or missing documents. For formal needs, see qualified appraisals.
Photo checklist
- Whole item from front, back, side, clasp, and underside.
- Close-ups of the diamond, side stones, prongs, setting, chips, abrasions, and repairs.
- Karat marks, maker marks, serial numbers, inscriptions, and certificate numbers.
- Lab report photos, receipts, boxes, prior appraisals, and insurance documents.
- Measurements and any known carat weight or grading details.
Market evidence note
A free screen can organize visible clues and next steps, but it is not a final appraisal. Sale records and catalog examples must be matched to the exact item, condition, originality, provenance, and current demand.
FAQ
Can you tell if a diamond is real from a photo?
Photos can suggest next steps, but they cannot prove diamond identity. Testing or lab documentation may be needed.
Do I need a GIA certificate?
Not always, but certificates can be important for larger, higher-value, colored, or resale-focused diamonds.
Does carat weight alone decide value?
No. Cut, color, clarity, treatment, certification, setting, condition, and market demand all matter.
Should I remove a diamond from a setting before appraisal?
No. Photograph it as-is first. Removing stones can create risk and is not always necessary.
