The popularity of lab grown diamonds has skyrocketed in recent years, and many buyers want to understand how to identify lab grown diamonds with confidence. Whether you’re purchasing an engagement ring, a gift, or a luxury piece for yourself, knowing how to distinguish lab grown diamonds from natural ones helps ensure transparency, trust, and value. Brands like AYAANI, known for their breathtaking 9K, 14K, and 18K lab grown diamond jewellery, are making the buying process even more exciting and accessible.

What Are Lab Grown Diamonds?

Lab grown diamonds are real diamonds, created in highly controlled laboratory environments using advanced technology.

How Lab Grown Diamonds Are Created (CVD & HPHT Methods)

• CVD (Chemical Vapor Deposition): A thin diamond seed grows layer by layer using carbon-rich gas.
• HPHT (High Pressure High Temperature): The method mimics Earth’s natural diamond-forming conditions.

Are Lab Grown Diamonds Real?

Absolutely. They have the same chemical composition, hardness, brilliance, and sparkle as mined diamonds. The only difference lies in origin, not beauty.

Why Identifying Lab Grown Diamonds Matters

Myths About Lab Grown Diamonds

Many assume lab diamonds are “fake,” but they’re not. They’re carbon-pure, conflict-free, and scientifically advanced.

Benefits of Choosing Lab Grown Diamonds

• Eco-friendly
• Ethical and conflict-free
• 40–60% more affordable
• Visually identical to natural diamonds

How to Identify Lab Grown Diamonds (Complete Guide)

Below are the top methods experts use to identify lab grown stones.

1. Check the Diamond Certification

Lab grown diamonds from reputable brands usually come with certifications from:

• IGI
• GIA
• SGL

Understanding Laser Inscriptions

Most lab grown diamonds have tiny laser inscriptions on the girdle indicating:

• “LAB GROWN”
• Serial number
• Certification reference

You can view this using a jeweller’s loupe.

2. Examine Under Magnification

Growth Patterns & Inclusions

Lab grown diamonds sometimes show features like:

• Metallic inclusions (HPHT)
• Parallel growth patterns (CVD)

These are visible under 10x magnification by a trained gemologist.

3. Look for Fluorescence Traits

Some lab grown diamonds display stronger fluorescence, often blue or yellowish tones, under UV light. While not a definitive method, it offers clues.

4. Use Specialised Diamond Testers

Thermal Conductivity Testers

These testers often cannot distinguish natural from lab grown, as both conduct heat similarly.

Electrical Conductivity Testers

Some advanced testers can detect HPHT diamonds due to their metallic traces.

5. Observe Colour Zoning & Grain Lines

CVD lab diamonds sometimes show visible colour zoning or straight growth lines, unlike natural diamonds.

6. Consult a Professional Gemologist

A certified diamond expert can perform a deeper analysis using:

• Spectroscopy
• Photoluminescence
• Microscopic inspections

This is the most reliable method.

Key Differences Between Natural & Lab Grown Diamonds

Visual Differences

To the naked eye, none.

Structural Differences

Growth patterns differ due to formation methods.

Price Differences

Lab grown diamonds typically cost 30–50% less than mined diamonds, offering more value for larger sizes.
