Lab grown diamonds and lab created diamonds are essentially the same thing - diamonds created in a laboratory using advanced technology that replicates the natural diamond formation process. Mined diamonds, on the other hand, are formed deep within the Earth over millions of years. Lab grown diamond rings and mined diamond engagement rings look aesthetically identical to the naked eye, having the same fire, brilliance, and sparkle. However, lab grown diamonds are a more ethical and sustainable option, as they don't involve mining.
Lab grown engagement rings are crafted with lab created diamonds, which have the same chemical, physical, and optical properties as mined diamonds. They are virtually indistinguishable without specialised equipment. Lab grown diamonds are also conflict-free and more environmentally friendly compared to mined diamonds.
Lab diamonds are genuine diamonds that are created in a lab, whereas diamond simulants, like cubic zirconia, are artificial stones that resemble diamonds but have different chemical and physical properties. Cultured diamonds, also known degradingly as synthetic diamonds or artificial diamonds, are essentially the same as lab grown diamonds.

Lab grown diamonds may have inclusions or trace elements trapped inside, just like mined diamonds. These minor differences are often not visible to the naked eye and require specialised equipment to detect.
Lab grown diamond engagement rings are generally more affordable than mined diamond rings due to the lower production costs and sustainable practices involved. Cullen Jewellery offers a range of high-quality, ethically crafted lab grown engagement rings at competitive prices.
The quality of a lab created diamond is determined by the 4Cs: carat weight, cut, clarity, and colour. These factors are similar to those used for evaluating mined diamonds.
