What Is Lab Grown Diamond Jewellery? Everything You Need to Know

Lab grown diamond jewellery has become one of the most talked-about trends in the jewellery world, especially among modern buyers who want beauty and modern jewellery designs. With increasing awareness, improved technology, and rising demand for sustainable luxury, more people are opting for lab-grown diamonds in rings, earrings, bracelets, and everyday jewellery pieces. 

• But what exactly are lab-grown diamonds? 
• Are they real? 
• How do they compare to natural diamonds? 
• And how do you choose the right piece?

This guide explains everything in a clear, simple, and informative way so anyone—from first-time buyers to repeat jewellery shoppers—can confidently understand and buy lab grown diamond jewellery.

1. What Are Lab Grown Diamonds?

Lab grown diamonds, also known as man-made or laboratory-created diamonds, are diamonds that are grown under controlled scientific conditions rather than being mined from the earth. The biggest thing people often ask is: Are lab-grown diamonds real diamonds?
The answer is YES—they are 100% real diamonds.

They have the same:
• Chemical structure (pure carbon)
• Crystal formation
• Hardness of 10 on the Mohs scale
• Brilliance, sparkle, and fire
• Durability

The only difference is their origin—natural diamonds take billions of years to form underground, while lab-grown diamonds are created using advanced technology within a few weeks.

There are two main processes used to create lab diamonds:

CVD (Chemical Vapour Deposition):
This process grows diamond crystals layer by layer using carbon-rich gas. CVD diamonds are known for high clarity and excellent brilliance.

HPHT (High Pressure High Temperature):
This method recreates the natural conditions of extreme heat and pressure under which diamonds form underground.

Both types produce genuine diamonds that are visually and physically identical to natural ones. That’s why lab grown diamond jewellery has become so popular—modern technology makes it possible to enjoy the same beauty at a fraction of the price.

2. About Diamond Shapes

Whether you choose a ring, pendant, bracelet, or pair of earrings, the shape of the diamond is one of the most important decisions. Each shape has its own personality, style, and sparkle pattern. Here are the most popular diamond shapes used in lab grown diamond jewellery:

Round Brilliant:
The classic choice. This shape gives the highest brilliance because of its 58 precisely placed facets. Perfect for engagement rings and everyday jewellery.

Princess Cut:
Square-shaped diamonds with sharp corners. They look modern, elegant, and very sparkly.

Oval:
A flattering shape that looks bigger than it actually is. Great for rings and pendants.

Cushion Cut:
Soft square shape with rounded corners. Romantic and vintage-inspired.

Emerald Cut:
Rectangular shape with step-cut facets. Known for a classy, mirror-like shine instead of intense sparkle.

Pear Shaped:
A teardrop design that looks sophisticated and elongates the fingers.

Marquise:
A long, pointed shape that gives maximum surface area, making the stone appear larger.

Radiant Cut:
A mix between the emerald and round cut, giving both structure and sparkle.

Each shape has its own charm, and buyers today choose based on personal style rather than trends. The best part is that lab-grown diamonds make even premium shapes more affordable, giving customers a wide range of choices.

3. Colour — How White Do You Want It?

Diamond colour is graded from D to Z, where:

• D–F = Colourless (brightest and most premium)
• G–J = Near colourless (great value, still very white)
• K–M = Slight warmth

For lab grown diamond jewellery, most customers prefer D to H colour grades because they balance beauty and budget.

If you want the whitest diamond with a stunning sparkle, D, E, and F are perfect. If you want maximum value without compromising appearance, G and H offer near-colourless beauty that looks white to the naked eye.

Because lab-grown diamonds are created using controlled environments, it’s easier to achieve higher colour grades without the steep pricing found with natural stones. This is one of the biggest reasons why shoppers love choosing lab-grown diamonds—they get premium quality without stretching their budget.

4. Certification

Just like natural diamonds, lab-grown diamonds should come with proper certification. Certification ensures that your diamond has been tested, graded, and authenticated by an independent laboratory.

The top certification bodies include:

• IGI (International Gemological Institute)
• GIA (Gemological Institute of America)
• SGL (Scientific Gemological Laboratory)

A certified lab-grown diamond comes with a detailed report showing:

• Carat
• Colour
• Clarity
• Cut
• Measurements
• Inscriptions
• Growth method used (CVD or HPHT)

Certification gives buyers confidence that they’re purchasing a high-quality, genuine diamond. Always look for certified lab grown diamond jewellery to ensure transparency and value.

6. Price — What’s a Fair Deal?

One of the biggest advantages of lab-grown diamonds is affordability. They offer the same beauty and brilliance as natural diamonds but at 40–70% lower prices. This makes them incredibly popular among Gen-Z, young couples, professionals, and the middle-class audience looking for luxury within budget.

Here’s why lab-grown diamonds are more affordable:

• No mining costs
• No rarity premium
• No supply-chain inflation
• Technology-driven production

A natural 1-carat diamond might cost 3 to 5 times more than a lab-grown diamond of the same quality. This is why many customers prefer lab-grown diamond jewellery for engagement rings and daily wear.

Gen-Z buyers especially appreciate:

• Sustainability
• Ethical sourcing
• Modern designs
• Better value for money
• Ability to buy bigger carat sizes within budget

Middle-class families appreciate that lab-grown diamonds allow them to gift or purchase premium jewellery without high financial pressure.
Overall, a fair deal should include:

• Certified stone
• Transparent pricing
• High-quality cut
• Return and exchange policies
• Authentic craftsmanship

7. Lab Grown vs Natural Diamonds — Why Lab Grown Are the Better Choice

When comparing lab-grown and natural diamonds, the main difference is their creation process—everything else remains the same.

Lab-Grown Diamonds Are:

• Real diamonds
•Sustainable
• Ethical
• Affordable
• Free from conflict mining
• Identical in physical and chemical properties

Natural Diamonds Are:

• Also real diamonds
• Formed underground over billions of years
• Much more expensive
• Limited in supply
• Often linked with mining impact

From a performance and appearance perspective, both types look exactly the same. Even professionals often need advanced tools to differentiate themselves.

But when we compare what modern buyers want—beauty, value, ethics, future-forward luxury—lab-grown diamonds clearly stand out. They allow customers to buy higher-quality jewellery without compromising on design, style, or budget.

This is why lab-grown diamonds have quickly become the preferred choice for millennials and Gen-Z across the world.
