Top 5 Brands to Shop Lab-Grown Diamonds Online

Looking for lab-grown diamonds? These 5 brands make online shopping easy, ethical, and stunning.

Introduction to Lab-Grown Diamonds

Lab-grown diamonds, also known as cultured diamonds or synthetic diamonds, are revolutionizing the jewelry industry. Created in a controlled laboratory environment using cutting-edge technology, these diamonds possess the same physical, chemical, and optical properties as natural diamonds. The magic lies in their composition—pure carbon arranged in a crystal structure, just like their natural counterparts.

What sets lab-grown diamonds apart is their affordability and sustainability. Unlike mined diamonds, which require extensive natural resources and can be associated with conflict and human rights issues, lab-grown diamonds are produced with a significantly lower environmental impact. This makes them an ethical choice for the modern consumer who values both beauty and responsibility.

Understanding the Basics of Lab-Grown Diamonds

Creating lab-grown diamonds is a fascinating blend of science and art, achieved through two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

The HPHT process mimics the natural formation of diamonds deep within the Earth’s mantle. A diamond seed is subjected to extreme temperatures and pressures, causing carbon atoms to bond and form a diamond crystal. This method is known for producing large, high-quality diamonds with excellent clarity grades and diamond color.

On the other hand, the CVD process is a marvel of modern technology. It involves placing a diamond seed in a chamber filled with a gas mixture. Carbon atoms from the gas deposit onto the seed, layer by layer, creating a diamond crystal. This process operates at lower temperatures and pressures compared to HPHT, making it more energy-efficient.

Both methods produce diamonds that are optically identical to natural diamonds, with the same carat weight, clarity grades, and diamond color. Whether created through HPHT or CVD, lab-grown diamonds are real diamonds, offering the same brilliance and durability as those formed over billions of years in the Earth’s mantle.

Let’s be honest — diamonds are stunning, but their sourcing? Not always sparkly. That’s why lab-grown diamonds are booming, expected to dominate 10% of the diamond market by 2030 (Bain & Co.).

They’re real, ethical, and easy on your wallet. But here’s the thing: not all brands are built the same. Some shine. Others… not so much.

So if you’re shopping online and want brilliance without the baggage, we’ve narrowed it down to the top 5 lab-grown diamond brands that are actually worth your time (and money).

Why Lab Grown Diamonds Are Taking Over the Jewelry Market

• More people are choosing lab grown diamonds over natural diamonds. Why? Because they look the same, but cost less.

• Lab diamonds are made in a controlled laboratory environment using smart science. Unlike mined diamonds that form through natural growth deep within the earth, lab grown diamonds are created using advanced technology in a lab.

• But just like in mining, lab processes begin with rough diamonds before they are cut and polished. Lab grown diamonds are polished with the same tools as natural diamonds before being brought to market.

• These grown diamonds have the same physical properties as real diamonds. In fact, even experts can’t tell the difference without tools!

In 2023, lab grown diamonds made up over 10% of global diamond sales (Bain & Co.). That number is growing fast.

💬 “They’re real, just made differently,” says GIA-certified gemologist Jessica Fields. “It’s like tech versus tradition.”

Understanding Lab Created Diamonds: What Makes Them Different?

Lab created diamonds, also called lab grown diamonds, are not fake. Cultured diamonds is another term for lab grown diamonds, often used in the jewelry industry to highlight ethical sourcing. They are real diamonds made in a lab using two science-backed methods — HPHT and CVD.

These diamonds have the same physical properties as natural diamonds. That means they look, sparkle, and last just like the ones found underground. Even trained gemologists often can’t tell the difference without a microscope.

💬 “Lab-grown diamonds are chemically and optically identical to natural diamonds. The only difference is how they’re made,” says GIA gemologist Susan Helmich.

HPHT (High Pressure High Temperature)vs CVD (Chemical Vapour Deposition): Two Processes that Create Diamonds

The High Pressure High Temperature (HPHT) Method Explained

HPHT stands for High Pressure High Temperature. Scientists recreate the same high temperature and same pressure found deep in the Earth’s mantle. That helps carbon atoms bond and form a diamond. HPHT can also improve color and clarity grades in diamonds.

• Mimics how natural diamonds are made

• Involves heat of over 1,300°C and pressure of over 5 GPa

• Great for creating large, clear diamonds

• Often used to make gem quality diamonds

• In the HPHT process, natural graphite is used as the raw material to create diamonds under extreme conditions.

What Is the Chemical Vapour Deposition (CVD) Process?

It means Chemical Vapor Deposition. Here, a tiny diamond seed is placed in a special machine. The machine fills with gas and heat — that’s the CVD process. The carbon slowly sticks to the seed and diamonds are created, layer by layer.

Modern labs use high-tech methods to produce diamonds that match the same structure as natural ones. The growth time for lab grown diamonds using CVD or HPHT is significantly shorter than the millions of years it takes for natural diamonds to form.

• Starts with a diamond crystal seed. Each lab process begins with a diamond seed, which slowly grows into a completely new diamond.

• Grows the diamond using gas and plasma

• Uses less energy than HPHT

• Popular for lab grown diamond jewellery and engagement rings

Frequently Asked Questions About Lab Grown Diamonds

1. Are they chemically identical to mined diamonds?

• Yes, lab grown diamonds are made of pure carbon atoms arranged in a crystal structure, just like natural diamonds. Chemically, they are identical to mined diamonds.

• The only difference is where they are made—one is from the earth, the other is from a lab setting using cutting edge technology.

2. Are Laboratory-Grown Diamonds Real Diamonds?

• Absolutely. Lab grown diamonds are real. They’re not diamond simulants like cubic zirconia or synthetic diamond substitutes.

• Lab diamonds go through the same diamond grading process as mined ones and often come with IGI or GIA certificates. Each lab-created diamond test is certified by gem labs to ensure it meets the same standards as mined diamonds.

3. Do they last as long? What about clarity and durability?
