Green lab-grown diamonds are classified as “fancy” coloured diamonds that are created in a laboratory rather than mined from the earth. These diamonds are chemically and physically identical to naturally formed diamonds. Through advanced technology, scientists have developed processes that replicate the extreme pressure and temperature conditions found deep within the Earth, where natural diamonds form. The resulting diamonds possess the same hardness, brilliance, and overall physical properties as natural diamonds.

All of our green lab-grown diamonds are certified by independent gemmological laboratories, just like natural earth-mined diamonds. Our fancy coloured lab-grown diamonds are sourced from overseas suppliers, with all listed prices inclusive of customs fees, GST, and postage — with nothing further to pay.

Green lab-grown diamonds are typically created using either the High Pressure High Temperature (HPHT) method or the Chemical Vapour Deposition (CVD) method. Various techniques and trace elements may be used during the growth process to achieve the diamond’s green colouration. Once grown, the diamond is then cut, polished, and professionally graded. Lab-grown green diamonds are often considered an ethical and environmentally conscious alternative to natural earth-mined green diamonds.

Most lab-grown green diamonds undergo some form of post-growth treatment after formation. These treatments are used to further enhance or stabilise the diamond’s colour. A diamond’s grading certificate will generally indicate whether any post-growth treatment has been detected.

Colours: Like naturally formed green diamonds, lab-grown green diamonds are available in a wide range of colour variations, including light green, fancy green, yellowish green, bluish green, and other unique colour combinations. Some colour variations can even resemble the appearance of Australian parti sapphires.
