Lab Grown Diamonds Brisbane

GS Diamonds offers Brisbane's biggest and best selection of lab grown diamonds — and has been at the forefront of the lab grown diamond movement in Brisbane for nearly a decade. 

Lab grown diamonds are chemically, physically, and optically identical to natural diamonds. The difference is imperceptible to the naked eye and virtually indistinguishable even to a trained jeweller under a microscope. Created using state-of-the-art technology that replicates the extreme heat and pressure conditions found deep within the earth, lab grown diamonds are just as real as their mined counterparts — and often of superior quality thanks to the highly controlled production environment. 

Choosing a lab diamond in Brisbane comes with some significant advantages: 

• Cost-effective — lab grown diamonds offer exceptional value compared to natural diamonds of comparable size and quality. 

• Environmentally conscious — each carat produced saves approximately 65kg of CO2, 57kg of air pollution, and 227 tonnes of displaced earth. 

• Ethically sourced — free from the conflict and questionable practices associated with some diamond mining operations. 

• Certified and graded — every stone is assessed using the same 4Cs framework as natural diamonds: Cut, Clarity, Colour, and Carat. GS Diamonds Brisbane lab grown diamonds are certified by IGI. 

At GS Diamonds Brisbane, our growing range includes natural and lab grown alternatives across every collection, giving you the freedom to choose the option that best suits your values and budget — without compromising on beauty or quality.
