How to Verify a Diamond Using Just Your iPhone

When buying a lab grown or natural diamond, verification matters. Every certified diamond comes with a laser-inscribed ID number on the girdle — but many buyers assume you need professional tools to see it.

Good news: you don’t.

With the macro camera feature on the iPhone 13 Pro Max, you can clearly see the IGI inscription on lab grown diamonds and grading report numbers on natural diamonds — right from your phone.

🔍 What Is a Diamond IGI ID?

For lab grown diamonds, IGI (International Gemological Institute) laser-etches a unique ID number on the diamond’s girdle.
For natural diamonds, grading reports from IGI or GIA include similar laser inscriptions.

This ID allows you to:

• Confirm authenticity
• Match the diamond to its certificate
• Verify details like carat weight, cut, color, and clarity

🔬 Traditional Method: Jeweler’s Loupe

Traditionally, jewelers use:

• 30x magnification loupe
• 60x magnification loupe

While effective, these tools aren’t always accessible to everyday buyers.

📱 Modern Method: iPhone 13 Pro Max Macro Camera

The iPhone 13 Pro Max introduced a powerful macro photography mode, allowing you to focus extremely close to small details — including laser inscriptions on diamonds.

With proper lighting and steady hands, you can:

• Zoom into the girdle
• Capture the IGI or GIA ID clearly
• Pause and read the inscription

👉 This works for both lab grown and natural diamonds.

🌐 How to Verify the Diamond ID Online

Once you see the inscription:

• Lab Grown Diamonds
  Enter the number on the official IGI website to view the grading report.
• Natural Diamonds
  Use the appropriate certification site (IGI or GIA) to confirm authenticity.

This instantly confirms that the diamond you’re holding matches its certificate.
