FAQ's

Some of the most common Q&A's

GIA certified means the diamond has been graded by the Gemological Institute of America, an independent laboratory that assesses cut, colour, clarity and carat weight. The GIA report confirms those grades and includes a unique report number you can check on the GIA website. At Marlows Diamonds, every certified diamond comes with its report, so you can match the stone to the document before you buy.
Start with a slightly lower clarity grade such as SI1 or SI2, which can look clean to the eye and cost less than higher grades. Prioritise an excellent cut over a larger carat, and consider a near-colourless grade like E to K. Marlows Diamonds offers GIA certified rings at up to 70% off high street prices, and you can book an appointment to compare stones in person.
Yes. GIA issues reports for lab-grown diamonds, and those reports state the growth method and clearly identify the stone as lab-grown. Lab-grown diamond engagement rings from Marlows Diamonds are GIA certified, so you get the same independent verification as natural diamonds, often at a lower price for the same carat and cut.
