Lab Grown

Our lab grown diamonds are a stunning choice if you are looking for an eye-catching diamond which is both affordable and ethically sourced.

As the newest addition to our Promise Collection, lab grown diamonds are undeniably captivating. Available in a range of shapes, these diamonds are an amazing alternative to a natural diamond.

IGI certified, these diamonds are grown in controlled environments which ensure the consistent quality and purity of the diamond. This alternative allows you to purchase your dream diamond without any reason for concern toward its environmental and ethical impact.

Along with its positive environmental influence, our lab grown diamonds are both customisable and affordable. With a variety of eye-catching shapes, colours and sizes, lab grown diamonds make it easy to find something that is uniquely you.

With extensive variety, these diamonds are also typically more affordable than the traditional natural diamond. With larger diamonds and higher quality for a lower price, lab grown diamonds are an irresistible choice.


Classic (non-certified)

Our stunning Classic (non-certified) diamonds are a captivating choice for those looking for a diamond which is eye-catching and affordable. Visually identical to certified diamonds when viewed with the naked eye, these diamonds are an irresistible choice for many.

Our Classic diamonds are non-certified; however, this does not decrease the genuine quality of the diamond. Non-certified diamonds have simply not been certified by a recognised certification body unlike our Premium, Certified and Lab Grown options.



Our Certified diamonds are scientifically analysed and certified by the International Gemological Institute (IGI). IGI provides an incredibly precise description of each diamond and its quality, using state-of-the art equipment and following the strictest international system.

A certification by IGI ensures that you can feel confident in your diamond of choice, knowing that it has been assessed by a highly meticulous certification body.



Our Premium Collection diamonds are certified by the Gemological Institute of America (GIA). The GIA is widely considered to be the world’s foremost authority in diamond certification.

GIA ensures each diamond is inspected by four expert graders and gemmologists, priding themselves in their highly accurate assessments and consistent grading.
