frequently asked questions

What is the difference between Lab Grown and Natural Diamonds? icon

Lab grown diamonds are based on advanced technology in the diamond industry. 
Using the same carbon crystal as a natural diamond, a laboratory mimics
the same pressure as the earth and within weeks to months a diamond is formed.
Due to its controlled environment colour and clarity is usually of the highest
standard. Due to the abundance of Lab grown diamonds being manufactured around the world they are 30–70% cheaper than natural diamonds.

Over billions of years natural diamonds are formed within the earth’s crust. 
Natural diamonds typically hold better value and are more expensive due to rarity and mining process. Natural diamonds are available in a wide variety of natural colours and inclusions which are part of the character of each unique diamond.

Are these stones certified for quality and authenticity? icon

Yes. Every Lab by Cerrone diamond is independently graded, answering the demand for certified lab-grown diamonds in Australia. Certification verifies cut, colour, and carat for complete transparency and added buyer confidence.

Do natural diamonds hold their value better than lab-grown diamonds? icon

When it comes to natural vs lab-grown diamond value, it’s important to remember that an engagement ring’s worth lies in its emotional significance and the care behind its creation. In saying that, natural diamonds are considered more enduring in value due to their rarity. Lab-grown diamonds, on the other hand, offer exceptional size and quality with the same budget.

Should I buy a Natural or Lab grown diamond engagement ring? icon

For generations, diamonds have been the ultimate symbol of love and commitment.  Traditionally consumers have only known a natural diamond, one that has been grown in the earth over billions of years contributing to their desire and rarity.  

In recent years, the development of advanced technology resulting in lab grown diamonds have consumers questioning which one to buy.  There are factors like price and value, rarity and mass production, tradition and modernization. However,
ultimately to comes down to the consumer’s preference. 

Can I create a bespoke lab-grown engagement ring? icon

Absolutely. Cerrone’s bespoke engagement rings Sydney service allows you to customise every detail — from diamond cut and setting style to metal type and engraving — creating a truly one-of-a-kind ring that reflects your love story.

What are the biggest lab‑grown diamond engagement ring trends for 2026? icon

Leading trends include hidden halo settings, unique diamond shapes such as oval, pear, and emerald, and low‑profile solitaires that balance elegance with everyday wearability.

The Fusion of Italian Artistry and Modern Innovation

For over five decades, Cerrone has defined Australian luxury through a rare combination of Italian-inspired artistry and contemporary innovation. Lab by Cerrone extends that heritage into a new era of conscious design, uniting hand-finished craftsmanship with the technological innovation of laboratory-grown diamonds.

Each ring in our Lab by Cerrone collection is shaped within Australia’s premier jewellery workshop, where our master jewellers oversee every detail from stone selection to polish. The result is a collection that answers the search for luxury engagement rings while honouring the legacy of Cerrone craftsmanship. 

Handcrafted Excellence from Australia’s Premier Boutique

Every Lab by Cerrone ring is created under the guidance of in-house artisans, not mass-produced offshore. From the forging of precious metals to the precise setting of each stone, the process reflects the values behind a truly handcrafted engagement ring in Australia.

Clients experience a boutique consultation that is personal and considered, with customisation options that extend beyond selecting a diamond. 

Defining New Standards in Sustainable Luxury

Lab-grown diamonds represent a refined evolution in fine jewellery. Produced in controlled environments that replicate natural diamond formation, they offer an ethical and environmentally responsible alternative to mined stones.

For couples seeking a sustainable engagement ring in Australia, Lab by Cerrone provides traceable and transparent certification without sacrificing brilliance and durability.

The Brilliance of Choice: Why Select a Lab-Grown Diamond?

A lab-grown diamond is chemically, physically, and visually identical to its mined counterpart. It possesses the same fire, hardness, and light performance, yet offers greater flexibility in size and specification within a considered budget.

When you compare lab diamonds vs mined diamonds, the distinction lies not in the appearance but in origin and value allocation. It is a compelling option for modern buyers exploring the benefits of lab-grown diamonds without compromising on elegance or symbolism.

Iconic Silhouettes for the Contemporary Bride

Lab by Cerrone showcases a spectrum of designs suited to every aesthetic preference. From sculptural solitaires to luminous halos and refined three-stone compositions, each lab-grown engagement ring style balances visual impact with enduring wearability.

Personal consultations allow each silhouette to be tailored to individual taste to create a ring that reflects both personality and style.

Masterfully Cut Solitaires and Intricate Pavé Settings

A precisely cut solitaire reveals the full beauty of a lab-grown diamond, maximising light return through expert faceting and proportion. Seeking elevated glamour?  Pavé and halo designs introduce layers of brilliance that amplify visual presence.

Whether it’s a pavé lab diamond ring or a classic solitaire lab-grown diamond, every detail is refined within our Cerrone workshop to ensure durability, comfort, and structural integrity.
