Lab-Grown Diamonds Australia
Discover what Lab-Grown diamonds are, how they are created, why they are real diamonds and what to check before choosing one for an engagement ring or fine jewellery.
Real Diamond. Modern Origin.
Lab-Grown diamonds have the same carbon crystal structure, hardness and optical beauty as mined diamonds. Their main difference is where they form.
What Are Lab-Grown Diamonds?
Lab-Grown diamonds are diamonds created in controlled laboratory environments using advanced technology that recreates the conditions in which diamonds form.
They are made from carbon and develop the same crystal structure as mined diamonds. When cut and polished, they display the brilliance, fire and scintillation associated with fine diamonds.
Lab-Grown diamonds are not cubic zirconia, glass or moissanite. Those are diamond alternatives with different compositions and properties.
How Are Lab-Grown Diamonds Made?
The two principal growth methods are CVD and HPHT. Both produce real diamond crystal that is later cut, polished and graded.
CVD: Chemical Vapour Deposition
A thin diamond seed is placed inside a chamber containing carbon-rich gas. Energy breaks down the gas, allowing carbon atoms to build gradually on the seed and form diamond crystal.
HPHT: High Pressure High Temperature
This process uses intense pressure and heat to recreate natural diamond-forming conditions. Carbon material grows around a diamond seed until a crystal forms.
Are Lab-Grown Diamonds Real Diamonds?
Yes. Lab-Grown diamonds are real diamonds. They share the same carbon composition, crystal structure, optical behaviour and hardness as natural diamonds.
They can be graded for the same 4Cs and may receive independent laboratory certification confirming their specifications and growth origin.
What Makes Them Diamonds?
Understanding the 4Cs
Lab-Grown diamonds are evaluated using the same four quality factors used for natural diamonds.
Cut
Controls how effectively the diamond reflects light. Cut quality is one of the strongest influences on visible sparkle.
Colour
Measures how colourless the diamond appears. D–F grades deliver a bright, premium white appearance.
Clarity
Describes internal and external characteristics. VS–VVS grades commonly appear clean to the unaided eye.
Carat
Measures diamond weight. Shape, dimensions and proportions determine how large the stone looks when worn.
Benefits of Lab-Grown Diamonds
Real-Diamond Beauty
Enjoy the classic brilliance, fire and visual character of a genuine diamond.
Strong Modern Value
A defined budget may allow a larger carat weight, stronger colour or higher clarity than a comparable natural diamond purchase.
Independent Certification
Many centre stones are graded by recognised laboratories such as IGI, where applicable.
Exceptional Durability
Lab-Grown diamonds rank 10 on the Mohs scale and are suitable for jewellery worn every day.
Wide Design Choice
Available in popular shapes including round, oval, pear, emerald, marquise, cushion and radiant.
Transparent Origin
The stone’s laboratory-created origin can be clearly identified through grading information and product disclosure.
IGI Certification and Quality
An independent grading report helps confirm the diamond’s measurable specifications and growth origin.
Many Pear Jewels Lab-Grown diamond centre stones are IGI certified where applicable, helping customers compare diamonds with greater clarity and confidence.

How to Buy a Lab-Grown Diamond in Australia
Do not choose by carat weight alone. The best-looking diamond is usually the result of balanced specifications and strong craftsmanship.
Choose a comfortable spend before comparing carat weight and setting styles.
A well-cut diamond will usually appear brighter and more lively.
Select the silhouette that best suits the wearer’s personal style and finger proportions.
D–F colour and VS–VVS clarity provide premium options, but visual balance matters more than any one grade.
Check the grading report and verify the stone’s dimensions, grades and origin.
Make sure the ring design protects the diamond and suits the wearer’s lifestyle.
Professional sizing is the most reliable option before ordering.
Review made-to-order timeframes, delivery details and after-sales support.

Lab-Grown Diamond FAQs
Are Lab-Grown diamonds real diamonds?
Yes. They have the same chemical, physical and optical properties as mined diamonds.
What is the difference between Lab-Grown and natural diamonds?
The main difference is origin. Natural diamonds form beneath the earth, while Lab-Grown diamonds are created in controlled laboratory environments.
Do Lab-Grown diamonds sparkle like mined diamonds?
Yes. Sparkle depends primarily on cut quality and proportions rather than diamond origin.
Are Lab-Grown diamonds good for engagement rings?
Yes. Their beauty, hardness and durability make them highly suitable for engagement rings worn every day.
Can Lab-Grown diamonds be IGI certified?
Yes. IGI commonly grades Lab-Grown diamonds and reports their carat, colour, clarity, measurements and growth origin.
Are Lab-Grown diamonds the same as moissanite?
No. Lab-Grown diamonds are carbon diamonds. Moissanite is a separate gemstone made from silicon carbide.
How hard are Lab-Grown diamonds?
They rank 10 on the Mohs hardness scale, the same as natural diamonds.
Do Lab-Grown diamonds become cloudy?
No. The diamond itself does not normally become cloudy. Surface oils, lotions and soap can reduce sparkle until the jewellery is cleaned.
Can a jeweller tell whether a diamond is Lab-Grown?
Lab-Grown and natural diamonds can look visually identical. Specialist testing and grading information may be required to confirm growth origin.
Do Lab-Grown diamonds pass a diamond tester?
They generally test as diamond using standard thermal testing because they are real diamonds. Specialist equipment may be needed to identify origin.
Are Pear Jewels Lab-Grown diamonds certified?
Many Pear Jewels Lab-Grown diamond centre stones are IGI certified where applicable. Review the individual product details for confirmation.
Which colour and clarity should I choose?
Pear Jewels commonly offers premium D–F colour and VS–VVS clarity options. The best combination depends on budget, shape and visual preference.
Can I customise a Lab-Grown diamond engagement ring?
Yes. You can personalise the diamond shape, carat weight, metal colour and setting through a custom design process.
How should I clean a Lab-Grown diamond ring?
Use warm water, mild soap and a soft brush. Rinse carefully and dry with a lint-free cloth.
