What Are Lab Diamonds?

A Modern, Ethical & Brilliant Choice

Diamonds have always symbolised love, commitment, and timeless beauty. Today, a new generation of diamonds is redefining how people celebrate these moments - Lab Diamonds, also known as Lab Grown Diamonds, Lab Created Diamonds, or lab-manufactured diamonds.

At Southern Star Diamonds, we believe that choosing a diamond should feel empowering, transparent, and aligned with your values. Lab diamonds offer the same breathtaking beauty as mined diamonds, while embracing innovation, ethics, and exceptional value.

What Are Lab Diamonds?

Lab diamonds are real diamonds that are grown in advanced laboratory environments rather than mined from the earth. They are created using cutting-edge technology that replicates the natural conditions under which diamonds form high pressure and high temperature, or controlled chemical vapor processes.

The result is a diamond that is chemically, physically, and optically identical to a natural diamond. The sparkle, hardness, brilliance, and durability are the same. The only difference is where the diamond is formed, not what it is.

That’s why lab diamonds are recognised by gemological laboratories and certified using the same grading standards as natural diamonds.

Are Lab Grown Diamonds Real Diamonds?

Yes - absolutely.

Lab-grown diamonds are 100% real diamonds.

They are not cubic zirconia or moissanite. They are not imitations or “fake” stones. Lab diamonds have the same:

  • Carbon crystal structure
  • Hardness (10 on the Mohs scale)
  • Fire, brilliance, and sparkle

Longevity and durability 

Even professional gemologists require specialised equipment to distinguish lab-grown diamonds from mined diamonds.

How Are Lab Created Diamonds Made?

There are two primary methods used to create lab-manufactured diamonds:

1. HPHT (High Pressure High Temperature)

This method recreates the intense heat and pressure found deep within the Earth. Carbon is exposed to these conditions, allowing it to crystallise into a diamond over time.

2. CVD (Chemical Vapour Deposition)

CVD uses a carbon-rich gas placed in a controlled chamber. Carbon atoms slowly bond layer by layer, forming a diamond crystal with exceptional clarity and control.

Both methods produce high-quality diamonds that are graded and certified independently.

Lab Diamonds vs Natural Diamonds

One of the most common questions we hear is: What’s the difference between lab diamonds and natural diamonds?

Appearance & Quality

There is no visible difference. Lab diamonds sparkle just as brilliantly and can achieve the same cut, colour, and clarity grades as mined diamonds.

Price

Lab diamonds typically cost 30–70% less than natural diamonds of comparable quality. This means you can choose a larger or higher-grade diamond without increasing your budget.

Ethics & Sustainability

Lab-grown diamonds are widely considered a more ethical and environmentally conscious option, as they avoid mining and have a smaller environmental footprint.

Certification

Lab diamonds are graded and certified by the same respected laboratories, using the same 4Cs.

Why Choose Lab-Grown Diamonds?

Lab diamonds are growing in popularity across Australia and globally - and for good reason.

Exceptional Value

With lab-grown diamonds for sale at significantly lower prices, you get more diamond for your money without sacrificing beauty or quality.

Ethical Confidence

Lab-created diamonds are conflict-free by nature, offering peace of mind to couples who value responsible sourcing.

Design Freedom

Because lab diamonds are more affordable, they open the door to custom designs, larger centre stones, and more intricate settings.

Future-Focused Choice

Lab manufactured diamonds represent innovation, technology, and progress - making them a meaningful choice for modern love stories.

Are Lab Diamonds Certified?

Yes.
All lab grown diamonds we offer are independently certified by internationally recognised

gemological laboratories such as IGI or GIA. Certification confirms:

  • The diamond is lab-grown 
  • Accurate grading of cut, colour, clarity, and carat 
  • Authenticity and quality 

A certified lab diamond gives you complete transparency and confidence in your purchase.

Do Lab Diamonds Last Forever?

Yes.

Lab diamonds are just as durable as mined diamonds and are designed to last a lifetime - and beyond. They will not fade, cloud, or lose their brilliance over time.

With proper care, lab diamonds can be passed down through generations, just like traditional diamonds.
