What Is Lab Grown Diamond Jewellery?

If you've recently started looking for diamond jewellery, you've probably come across the term Lab Grown Diamond Jewellery. Many people wonder whether these diamonds are real, how they're made, and whether they're worth buying.

The simple answer is yes lab grown diamonds are real diamonds.

The only difference is where they are created.

Because of this, Lab Grown Diamond Jewellery has become a popular choice for people who want premium-quality diamond jewellery without paying the premium price of mined diamonds.

Whether you're shopping for a ring, necklace, earrings, bracelet, or pendant, lab grown diamonds offer the same elegant look while giving you more value for your money.

  •  They are available in a wide range of designs and sizes.

  •  They are a more sustainable choice.

  •  They are certified just like natural diamonds.

Are Lab Grown Diamonds Real?

Yes, lab grown diamonds are 100% real diamonds.

What Is Lab Grown Diamond Jewellery Made Of?

One of the most common questions buyers ask is, "What is lab grown diamond jewellery made of?"

The answer is simple.

A lab grown diamond is made from pure carbon, just like a natural diamond. The diamond itself is then set into precious metals such as:

  • 14K Gold

  • 18K Gold

  • White Gold

  • Rose Gold

  • Platinum

  • Sterling Silver (in selected designs)

The jewellery setting depends on the design and brand, but the diamond itself remains a real diamond with the same physical and optical properties as a mined diamond.

 


 

Why Buyers Are Switching to Lab Grown Diamonds

Buying diamond jewellery today is no longer just about tradition. Buyers want jewellery that fits their lifestyle, budget, and personal values.

Lab grown diamonds offer several practical advantages:

Whether you're buying your first diamond pendant or upgrading your jewellery collection, lab grown diamonds make luxury more accessible without compromising on beauty.

How Are Lab Grown Diamonds Made?

One of the biggest questions people ask is, "If lab grown diamonds aren't mined, how are they made?"

The answer is fascinating.

Scientists use advanced technology to recreate the same conditions under which natural diamonds form deep inside the Earth. Instead of taking billions of years, this process takes just a few weeks in a controlled laboratory.

There are two main methods used to create Lab Grown Diamonds.

1. High Pressure High Temperature (HPHT)

The HPHT method recreates the extreme heat and pressure found beneath the Earth's surface.

A tiny diamond seed is placed inside a machine where intense heat and pressure allow carbon atoms to grow around it, gradually forming a diamond crystal.

HPHT diamonds are known for:

  • Excellent durability

  • High brilliance

  • Premium quality

  • Suitable for fine jewellery

 


 

2. Chemical Vapour Deposition (CVD)

The CVD method is one of the most widely used techniques today.

In this process, a diamond seed is placed inside a special chamber filled with carbon-rich gases. These gases break down, allowing carbon atoms to slowly build layer by layer until a diamond is formed.

CVD diamonds are popular because they offer:

  • Exceptional clarity

  • Better control over quality

  • Modern manufacturing precision

  • Beautiful sparkle

Both methods produce real diamonds, not diamond substitutes.
