Our lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. The difference? They're created in controlled laboratory environments, allowing you to choose a larger, higher-quality stone for your budget.

Every diamond is sourced from certified suppliers and comes with full certification detailing cut, colour, clarity, and carat weight.

Sydney is the most expensive capital in the country to get engaged in, and lab grown diamonds are the clearest way to keep the ring you want within reach. The same budget simply goes further.

• Typically 50-70% less than mined: A lab-grown stone usually costs well under half the price of a mined diamond at the same cut, colour, clarity, and carat weight.
• Spend where it shows: Many Sydney buyers use the difference to step up a carat band or choose a more detailed lab grown solitaire engagement ring.
