Why choose lab-grown diamonds

Laboratory-grown diamonds suit people who want the look and character of a diamond, often at a larger size or higher specification for their budget.

Real diamonds, created in a laboratory

Lab-grown diamonds share the crystal structure of natural diamonds, and have nearly the same chemical, physical and optical properties. By eye they can be indistinguishable. Telling them apart takes advanced laboratory instruments.

Choosing with confidence

Neither natural nor lab-grown diamonds have guaranteed resale value, so choose the diamond that suits your budget and what you'd like to wear. We can compare natural and lab-grown options within your budget.

Grading certificates from IGI and GIA

IGI

Grades lab-grown diamonds using the 4Cs: cut, colour, clarity and carat weight.

GIA

Also issues reports for lab-grown diamonds. We list GIA-reported stones only when the report gives a colour and clarity grade.

A grading certificate is supplied with your diamond. Certificates from the two laboratories aren't directly comparable.

Lab-grown diamond FAQs

Are lab-grown diamonds real diamonds?

Yes. They have the same crystal structure as natural diamonds, and nearly the same chemical, physical and optical properties. They're created in a laboratory rather than formed in the earth.

Are lab-grown, lab-created and synthetic diamonds the same?

These terms all describe diamonds made in a laboratory. Some people also say man-made. They aren't simulants such as cubic zirconia or moissanite, which are different materials.

Can you tell them apart by eye?

They can be indistinguishable by eye. Telling them apart takes advanced laboratory instruments.

How are they graded?

IGI grades lab-grown diamonds using the 4Cs. Every diamond we list has a colour and clarity grade on its IGI or GIA report. A grading certificate is supplied with your diamond.

Do they cost less than natural diamonds?

For similar specifications, usually considerably less. Prices vary by stone, so the listing shows current prices.

Do they hold their value?

Neither natural nor lab-grown diamonds have guaranteed resale value. Choose the diamond that suits your budget and what you'd like to wear.

Can I return a lab-grown diamond?

Yes. Our 30-day return policy applies. The 30 days begin when you receive your diamond, and the policy's conditions apply.

How is my diamond delivered?

Lab-grown diamonds use the same delivery arrangements as other GoldeNet diamonds. See our shipping policy.

Can I have one set in an engagement ring?

Yes. Choose a lab-grown diamond, select Add To Ring, then choose a setting. We can also custom-make a ring.

Can I see a diamond in person?

You can visit our Melbourne showroom by appointment only, or contact us online.
