What is Lab-Grown Diamonds?

Lab-grown diamonds are meticulously crafted using cutting-edge technology that mirrors the natural diamond formation process, resulting in stones that are visually and chemically indistinguishable from their natural counterparts.

Federal Trade Commission Definition of Diamond:

The previous FTC definition described a diamond as “a natural mineral consisting essentially of pure carbon crystallized in the isometric system.” However, the word “natural” has since been removed.

The FTC explained, “The Commission no longer defines a ‘diamond’ using the term ‘natural’ because it is no longer accurate to limit diamonds to being ‘natural’ when products can now be created that possess essentially the same optical, physical, and chemical properties as mined diamonds.”

Differences between
Lab-Grown Diamond and Natural Diamond?

Lab-Grown Diamond

Natural Diamonds

Natural diamonds and lab-grown diamonds are virtually identical in appearance and chemical composition, but they differ in origin and certain characteristics:

1. Formation:

Natural Diamonds:
Formed over millions of years under high pressure and temperature deep within the Earth.

Lab-Grown Diamonds:
Created in a few months using advanced technology in controlled environments.

2. Key Differences:

Lab-grown diamonds lack nitrogen impurities, which is a distinguishing factor gemologists use to identify them.

Lab diamonds are typically up to 30% cheaper than natural diamonds of the same size and quality.

These differences make lab-grown diamonds a more affordable and sustainable option while maintaining the same brilliance and durability as natural diamonds.

While visually identical, these differences highlight the unique origins and production methods of each type of diamond.

How are diamonds made in a lab?

Lab-grown diamonds are created using two primary methods: CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature). Here's a breakdown:

1. HPHT Process:

How it works:
Pure carbon is exposed to extreme heat and pressure, mimicking natural diamond formation conditions.

Characteristics:
- Produces diamonds with minimal visible metal traces.
- Typically higher quality than CVD diamonds.
- Often does not require post-treatment.

2. CVD Process:

How it works:
A carbon-rich gas is ionized and deposited onto a diamond seed. Over weeks, the carbon crystallizes, forming a diamond.

Characteristics:
- May have brown undertones or graining.
- Often apply for creating 3 carat or above diamonds
- Often requires post-growth treatments to improve appearance.

Lab-grown diamonds are chemically and visually identical to natural diamonds. They are graded by third-party authorities such as GIA or IGI based on the 4C criteria.

Key Points for Best Value:

Cut: Choose an Excellent cut for maximum brilliance.
Color: Opt for D-F color (colorless range).
Clarity: Select VS2-SI1 clarity, which offers a balance between quality and price.

Production Timeline:

Lab-grown diamonds require 6-10 weeks to grow for a loose diamond.
After growth, they are cut and polished just like natural diamonds to achieve their final appearance.

HPHT vs CVD Diamonds

HPHT Diamonds:

Generally of higher quality.
Do not require post-growth treatments.

CVD Diamonds:

Fast-growing process may lead to internal marks and graining.
Often have brown-ish undertones, requiring additional treatment to enhance their appearance.

Certification and Grading

Lab-grown diamonds, like natural ones, are rigorously graded by labs such as GIA and IGI. They are assessed for cut, color, and clarity, ensuring they meet high standards.

Top Tip for Best Value

Look for lab-grown diamonds with:

Cut: Excellent
Color: D to F
Clarity: VS2 to SI1

This combination offers a stunning diamond at a reasonable price.

Lab-Created Diamonds: Overview

Formation:

Begins as a tiny carbon seed.
Exposed to extreme heat and pressure (HPHT) or undergoes a Chemical Vapor Deposition (CVD) process.
Mimics the natural diamond formation process.

Growth:

Typically grows in a laboratory within 6 to 10 weeks.

Final Steps:

Cut and polished in the same manner as natural diamonds.
