Brilliance you can feel good about wearing
A lab grown diamond carries the same fire, the same hardness, and the same certified quality as a mined stone — at a fraction of the cost.

Frequently Asked Questions
Still got questions? Perfect.
Everything you need to know about lab grown diamonds — from the science to the savings — answered right here.
Are Lab Grown Diamonds real diamonds?
Yes — completely and unequivocally. Lab grown diamonds have the same chemical composition (pure carbon, cubic crystal structure), the same physical hardness (10 on the Mohs scale), and the same optical properties as mined diamonds. Even a trained gemologist cannot tell them apart with the naked eye. The only difference is origin: one formed underground over billions of years, the other grown in a laboratory over a matter of weeks using either CVD (Chemical Vapour Deposition) or HPHT (High Pressure High Temperature) technology.
How much cheaper are lab grown diamonds compared to mined diamonds in Australia?
Lab grown diamonds typically cost 50–70% less than comparable mined diamonds in Australia. A 1-carat, VS1 clarity, F-colour round brilliant mined diamond might retail for $8,000–$12,000 AUD. The same specifications in a lab grown diamond will typically range from $2,500–$4,500 AUD. That's a real saving — money you could put towards a setting upgrade, a honeymoon, or simply keep in your account.
Do lab grown diamonds hold their value?
This is the honest answer: like most mined diamonds, lab grown diamonds are not a financial investment in the traditional sense — their resale value is lower than the purchase price. However, the significant savings at purchase mean you are getting far more diamond for your money upfront. If you're buying a diamond as a symbol of love, not as a stock portfolio, lab grown makes exceptional sense.
What is the difference between CVD and HPHT lab grown diamonds?
Both methods produce genuine diamonds, just through different processes. CVD (Chemical Vapour Deposition) grows diamonds from a carbon-rich gas in a chamber, layer by layer. HPHT (High Pressure High Temperature) replicates the extreme underground conditions that form natural diamonds. Both result in certified, gem-quality diamonds. CVD is more common for jewellery-grade stones and tends to allow more precise control over colour.
Can I get a lab grown diamond engagement ring custom-made in Australia?
Absolutely. We offer fully custom design services — you choose the diamond (cut, carat, colour, clarity), the metal (18ct yellow, white, or rose gold, or platinum), and the setting style. Our designers work with you from concept to finished piece, with a standard turnaround of 3–5 weeks. Custom rings are available for delivery anywhere in Australia.
How do I know what size diamond to buy?
Carat is a measure of weight, not size — but size and carat are closely related. As a rough guide:
- 0.5ct round brilliant ≈ 5.1mm diameter
- 1ct round brilliant ≈ 6.5mm diameter
- 1.5ct round brilliant ≈ 7.4mm diameter
- 2ct round brilliant ≈ 8.1mm diameter
Different cuts (oval, elongated shapes) can appear larger face-up for the same carat weight. Our team can help you find the sweet spot between size, quality, and budget.
Are lab grown diamonds ethical and sustainable?
Lab grown diamonds eliminate many of the most serious ethical concerns associated with diamond mining — including conflict financing, unsafe labour practices, and ecosystem destruction. They require no open-cut mining and produce significantly less land disruption. That said, they do require energy to produce — the most environmentally responsible producers use renewable energy sources. When buying, look for brands that are transparent about their energy sourcing.
Do you offer free shipping across Australia?
Yes. We offer free tracked and insured shipping to all Australian states and territories — including regional and remote areas. Orders over $500 are shipped via express courier with signature on delivery. All packaging is discreet and designed to protect the jewellery in transit.
