Frequently Asked Questions

What Is a lab grown diamond?

A lab grown diamond is a synthetic diamond created in a controlled environment using high-tech processes that mimic natural diamond formation.

Are lab grown diamonds real diamonds?

Lab-grown diamonds are technically and chemically the same as mined diamonds — they have identical physical, optical and chemical properties, and they can be graded by gemmological labs like IGI. However, unlike natural diamonds formed over billions of years deep within the earth, lab-grown diamonds are created in factories using advanced technology that replicates the natural growth process in a matter of weeks.

Because they are manufactured rather than mined, lab-grown diamonds are considered synthetic diamonds. While they may look and perform the same, they do not carry the same rarity, natural origin, or long-term value as natural diamonds — aspects that many clients consider when choosing a piece of fine jewellery.

Whether you prefer the timeless allure of a natural diamond or the affordability of a lab-grown option, the right choice depends on your personal values and priorities. We're happy to guide you through both options.

Do lab grown diamonds sparkle like natural diamonds?

Absolutely. Lab grown diamonds offer the same fire, brilliance and sparkle as their mined counterparts.

Are lab grown diamond engagement rings more affordable?

Yes. Lab grown diamonds are typically 40-50% more affordable than mined diamonds of similar size and quality.

Can I custom design a lab grown diamond ring?

Yes, we offer fully bespoke lab grown diamond rings, designed and handcrafted in our Sydney studio.

How long does it take to make a custom lab grown diamond ring?
