We tested 11 AI image generators so you don’t have to. Here’s what actually works.
The Short Answer
If you’re selling jewelry online and want AI-generated lifestyle photos, use one of these:
| Model | Best For | Cost | Our Verdict |
|---|---|---|---|
| Nano Banana Pro | Premium quality, zero failures | $0.15/image | Best choice |
| FLUX.2 Pro | High volume, good quality | $0.045/image | Best value |
| Nano Banana | Budget option, simple rings | $0.039/image | Good enough |
Skip these entirely: Qwen-Image, Runway Gen-4, Seedream 4, GPT Image 1.5
Why This Matters
Lifestyle product photos — showing your jewelry worn on a hand, around a neck, or styled in a scene — convert better than studio shots. But they’re expensive:
- Professional photographer: $50-200+ per shot
- DIY with models: Hours of time, inconsistent results
- Stock photos: Generic, not your actual product
AI image generation promises to change this. Upload a photo of your ring, get a lifestyle shot in seconds. But which AI actually works?
We tested 11 of the leading AI image generators on a simple task: generate a “ring on hand” product photo. The results were surprising.
The Test: 132 Images, 11 Models
We gave each model the same challenge:
- Here’s a photo of a ring
- Generate a lifestyle shot showing it worn on a woman’s hand
- The ring should be recognizable, the hand should look real
We tested 3 rings (simple, medium complexity, complex) across 4 different prompting approaches. That’s 132 total images, all evaluated blind (we didn’t know which model made which image while scoring).
What We Measured
- Ring accuracy: Does it match the reference?
- Hand quality: Does it look human?
- Placement: Is the ring actually on a finger?
- AI look: Would a customer notice it’s AI-generated?
- Usability: Would you publish this on your shop?
The Results: Clear Winners and Losers
The Winners
#1: Nano Banana Pro (Google)
- 85% of images were usable
- 0% rejected — literally never failed
- Perfect for complex jewelry
This is Google’s flagship image model. It costs more ($0.15/image) but it never produced an unusable result. For hero images, marketing materials, or complex pieces, it’s worth the premium.
#2: FLUX.2 Pro (Black Forest Labs)
- 69% usable
- Only 8% rejected
- Best balance of quality and cost
At $0.045/image, FLUX.2 Pro is our pick for most sellers. You’ll occasionally need to regenerate, but it’s 3x cheaper than Nano Banana Pro.
#3: Nano Banana (Google)
- 46% usable
- 8% rejected
- Good for simple rings
The budget Google option. Works well for straightforward pieces but struggles with intricate details.
The Losers
Qwen-Image & Runway Gen-4: 100% Failure Rate
Every single image from these models was rejected. They simply couldn’t reproduce the reference ring — they generated different rings entirely.
GPT Image 1.5: 58% Rejected
OpenAI’s image model surprised us (negatively). More than half the outputs were unusable. The ring style would be “inspired by” but not match the reference.
Seedream 4 & 4.5: 58-75% Rejected
ByteDance’s models couldn’t handle jewelry details. They work fine for other use cases, but not for precise product photography.
What Actually Improves Results?
Scenario: Replace > Generate
We tested two approaches:
- Generate from scratch: Give the AI just the ring photo and ask for a lifestyle shot
- Replace: Give the AI a hand photo WITH a ring, ask it to swap in your ring
Result: Replace works better (46% win rate vs 35%)
Why? When you provide a hand reference, the AI has more context. It knows exactly what pose, lighting, and style you want. It just needs to change the ring.
Recommendation: Find or generate a base hand photo you like, then use the Replace approach for all your rings.
Description: Doesn’t Help Much
We expected adding a text description (“gold ring with pear-shaped diamond…”) would improve accuracy. It didn’t.
- With description: 41% win rate
- Without description: 40% win rate
The reference image contains more information than words can convey. For complex rings, descriptions may actually hurt by adding conflicting details.
Recommendation: Keep prompts simple. Focus on the scene, not the ring details.
Ring Complexity: Simpler = Better
| Ring Type | Success Rate |
|---|---|
| Simple (plain band, signet) | 50% |
| Medium (single stone, basic setting) | 33% |
| Complex (multiple stones, intricate band) | 39% |
Simple rings have 50% higher success rates. If you’re new to AI photography, start with your simpler pieces.
Practical Workflow
Based on our research, here’s how to get started:
Step 1: Choose Your Model
- Quality priority: Nano Banana Pro ($0.15)
- Volume priority: FLUX.2 Pro ($0.045)
- Budget priority: Nano Banana ($0.039)
Step 2: Prepare Reference Images
- Use high-quality photos of your jewelry
- Clean white/neutral backgrounds work best
- Front-facing, well-lit shots
Step 3: Get a Base Hand Photo
Either:
- Generate one with AI (just once)
- Use a stock photo with appropriate license
- Photograph your own hand
This becomes your template for the Replace scenario.
Step 4: Generate with Replace Approach
Prompt structure:
Replace the ring in this photo with the ring from the reference image.
Keep the hand pose and lighting unchanged.
Step 5: Budget for Iterations
Even the best model doesn’t hit 100%. Plan for:
- Nano Banana Pro: 1.2x generations per usable image
- FLUX.2 Pro: 1.5x generations per usable image
- Nano Banana: 2x generations per usable image
Common Problems & Fixes
Problem: Ring doesn’t match reference
Cause: Model isn’t capturing the details from your reference image.
Fixes:
- Try a cleaner reference photo
- Use FLUX.2 Pro or Nano Banana Pro (they have better reference fidelity)
- Simplify: test with a simpler ring first
Problem: Wrong finger
Cause: Models often put rings on index or middle finger instead of ring finger.
Fixes:
- Specify “ring finger” in your prompt
- Use a hand reference photo where the ring is already on the correct finger
- Regenerate — this is somewhat random
Problem: Obviously AI-looking hands
Cause: Some models generate “uncanny valley” skin textures.
Fixes:
- Switch to Nano Banana Pro (best hand quality)
- Use the Replace approach with a real hand photo
- Check the “AI Look” rating before publishing
Problem: Ring floating or clipping into hand
Cause: The AI struggles with 3D geometry for complex rings.
Fixes:
- Simplify: test with simpler rings
- Use Replace approach (gives AI better spatial context)
- Regenerate and pick the best
Cost Comparison
For 100 product lifestyle photos:
| Model | Cost | Expected Usable | Regenerations Needed |
|---|---|---|---|
| Nano Banana Pro | $18 | 85 | ~15 |
| FLUX.2 Pro | $6.75 | 69 | ~45 |
| Nano Banana | $7.80 | 46 | ~54 |
Hidden cost: Your time reviewing and regenerating. Nano Banana Pro’s zero-failure rate means less manual work.
What We’re Testing Next
This study answered the baseline question: Can AI do this at all? Next, we’re investigating:
- Ideogram inpainting: Does the mask-based workflow beat these results?
- Consistency testing: Can winning models produce 10 good images in a row?
- Other jewelry types: Do bracelets, necklaces, and earrings work the same?
- Prompt optimization: Can we improve failing models with better prompts?
Bottom Line
AI jewelry photography works — but only with the right models. Use Nano Banana Pro for quality, FLUX.2 Pro for volume, and skip Qwen, Runway, and Seedream entirely.
Start with simple rings, use the Replace approach, and budget for some regenerations. You’ll be producing professional lifestyle shots at a fraction of traditional photography costs.
