Lab Grown vs Natural Diamond: Key Differences

When shopping for diamonds, you might wonder about the differences between a lab grown vs natural diamond. Both types are chemically and structurally identical, making them real diamonds. However, there are distinctions in how they are created, how they are identified, and their resale value. Let’s dive into these aspects to help you make an informed decision.

What Makes Lab Grown and Natural Diamonds Real?

Both lab grown and natural diamonds share the same carbon atom structure. This structure gives diamonds their renowned hardness and brilliance. The primary difference lies in their origin:

• Natural Diamonds: Formed deep within the Earth over billions of years due to intense heat and pressure.
• Lab Grown Diamonds: Created in a laboratory setting, typically within weeks or months, using methods like High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).

Both are real diamonds, not simulants like cubic zirconia or moissanite. Simulants are entirely different in composition and do not have the same physical properties.

How Labs Tell Lab Grown vs Natural Diamonds Apart

Advanced Testing Methods

While both types look identical to the naked eye, gemological labs use advanced techniques to distinguish them: learn about diamond testing tools for home and professional use.

1. Spectroscopy: Analyzes the light absorption patterns to detect specific features unique to lab grown diamonds.
2. Inclusion Patterns: Natural diamonds often have different types of inclusions than lab grown ones.
3. Fluorescence: Under UV light, lab grown and natural diamonds may fluoresce differently, helping to identify their origin.
4. Phosphorescence: Some lab grown diamonds display phosphorescence, which can be a telltale sign.

Certification

Grading labs like GIA (Gemological Institute of America) and IGI (International Gemological Institute) provide reports that clearly indicate whether a diamond is lab grown or natural. These reports offer peace of mind and are crucial for insurance and resale.

How the Difference Affects Resale Value

The resale market views lab grown and natural diamonds differently:

Natural Diamonds

• Value Retention: Generally hold their value better due to their rarity and historic appeal.
• Market Demand: Consistent demand, especially for large, high-quality stones.

Lab Grown Diamonds

• Price Point: Typically lower initial cost, making them attractive for budget-conscious buyers.
• Resale Challenges: May not retain value as well because they can be produced in unlimited quantities.

If you’re considering selling a diamond, obtaining an appraisal from an independent appraiser or a grading report from a reputable lab is recommended to assess its current market value. Learn more about what affects a diamond’s worth.

Using Diamond Tester for a Quick Check

Before you decide on a purchase or sale, consider using Diamond Tester. This app allows you to take a photo of your diamond, providing an AI-based estimate of whether it’s real and offering a preliminary assessment of its 4C grade. While not a substitute for a professional appraisal, it can be a useful first step.

FAQ

Are lab grown diamonds real?

Yes, lab grown diamonds are real. They have the same chemical composition and crystal structure as natural diamonds.

How can I tell if my diamond is lab grown or natural?

While at-home tests aren’t reliable, a professional grading report will clearly state the diamond’s origin. Use tools like Diamond Tester for a quick, preliminary check.

Do lab grown diamonds hold their value?

Lab grown diamonds generally have a lower resale value compared to natural diamonds, due to their ability to be produced in larger quantities.

Which is better: lab grown or natural diamond?

It depends on your priorities. Choose a lab grown diamond for affordability and ethical considerations, or a natural diamond for rarity and tradition.
