Visual Inspection Methods 👁️
🎨 Color Consistency & Zoning
| Sign | Natural Gemstone | Synthetic/Fake |
|---|---|---|
| Color | ✅ Slight variations, natural zoning | ❌ Perfectly uniform color |
| Intensity | ✅ Varies with light angle | ❌ Same from all angles |
| Zoning | ✅ Irregular, natural patterns | ❌ Too perfect or absent |
💡 Example: Queensland sapphires show natural color zoning that proves authenticity.
🔬 Inclusions (Natural vs Synthetic)
🌟 KEY INSIGHT: Inclusions are like fingerprints - they prove a stone is natural! Completely flawless stones are often synthetic.
| Type | What to Look For | Indicates |
|---|---|---|
| ✅ Natural | Organic patterns, irregular shapes, unique to each stone | Authentic gemstone |
| ❌ Synthetic | Gas bubbles (round), curved growth lines, too perfect | Lab-created or fake |

Simple At-Home Tests 🏠
💨 The Fog Test
| Step | What to Do | Result |
|---|---|---|
| 1️⃣ | Breathe on the stone | Creates fog/condensation |
| 2️⃣ | Watch how quickly fog clears | ✅ Real: Clears instantly ❌ Fake: Stays foggy longer |
Why it works: Real gemstones disperse heat quickly due to high thermal conductivity.
⚖️ Weight Comparison
Natural gemstones are denser than glass:
- ✅ Real amethyst: Feels heavier than glass of same size
- ✅ Real sapphire: Noticeably heavy for its size
- ❌ Glass imitation: Lighter, less substantial feel
🔨 Scratch Resistance (Mohs Scale)
⚠️ WARNING: Don't scratch valuable stones! This test can damage them. Only use on stones you're willing to risk.
| Gemstone | Hardness | Can Scratch | Cannot Scratch |
|---|---|---|---|
| Sapphire | 9 | ✅ Glass, quartz | ❌ Diamond only |
| Topaz | 8 | ✅ Glass | ❌ Sapphire, diamond |
| Amethyst | 7 | ✅ Glass | ❌ Topaz, sapphire, diamond |
