Understanding Certification and Quality with Visual Guides

💎 What Are Lab Grown Diamonds?

Lab grown diamonds are real diamonds created in controlled laboratory environments. They possess identical physical, chemical, and optical properties to natural diamonds.

Property Lab Diamonds Natural Diamonds
Chemical Composition Pure Carbon (C) Pure Carbon (C)
Hardness 10 on Mohs Scale 10 on Mohs Scale
Formation Time 2-4 Weeks Millions of Years
Environmental Impact Minimal Significant Mining
Price 30-50% Less Premium Pricing

4️⃣ The 4 Cs of Lab Diamond Quality

⚖️

Carat Weight

Measures the diamond's weight. 1 carat = 200 milligrams. Larger carats are exponentially more valuable.

✂️

Cut Quality

Determines brilliance and fire. Excellent cut maximizes light return for stunning sparkle.

🎨

Color Grade

Graded D-Z scale. D is colorless, Z has noticeable yellow tint. Most popular: D-J grades.

🔍

Clarity Grade

Internal characteristics visibility. FL (Flawless) to I3 (Included). VS+ recommended for engagement rings.

❓ Frequently Asked Questions

Are lab diamonds real diamonds?

Yes! Lab diamonds have identical physical, chemical, and optical properties to natural diamonds. They're made of pure carbon with the same crystal structure.

Can you tell the difference between lab and natural diamonds?

No, they're visually identical. Only advanced laboratory equipment can distinguish between them. Both pass standard diamond tests.

Do lab diamonds hold their value?

While they don't appreciate like rare natural diamonds, lab diamonds maintain functional value and are increasingly accepted in the market.

How long do lab diamonds last?

Forever! Lab diamonds are just as durable as natural diamonds with the same hardness rating of 10 on the Mohs scale.
