Tips for Accurate Analysis

Image Quality Matters

For best results:

Use high-resolution images (2048px+)
Multiple angles (front, side, top, back)
Well-lit with neutral lighting
Plain background (white/gray)
Include size reference (ruler, coin)

Provide Context

Help the AI with details:

Known metal type
Gemstone types (if known)
Approximate age or period
Designer or brand (if applicable)
Any documentation available

Ask Specific Questions

Better questions get better answers:

❌ “Tell me about this ring” ✅ “Estimate the total gold weight and identify the center gemstone type”

❌ “Is this valuable?” ✅ “Provide an estimated retail value based on current market prices”

Troubleshooting

Analysis seems inaccurate

Provide higher-quality images
Include multiple angles
Add known specifications
Request professional-tier analysis

CAD model doesn’t match design

Upload clearer reference images
Specify design details explicitly
Use 3D view from multiple angles
Contact support for manual review

Cost estimates vary widely

Market prices fluctuate
Regional differences apply
Labor rates vary by location
Use estimates as rough guidelines

Next Steps

After CAD analysis:

Use specifications to manufacture
Share reports with jewelers
Update design based on feedback
Create variations in Canvas
