Diamond Certification

When buying a diamond, it is an investment and should last forever. Only purchase diamonds and diamond jewellery from a reputable source, such as 28 Diamonds. Always make sure it is a certified stone, which means it must come with a lab certificate from a well-known diamond laboratory. At 28 Diamonds, we only supply stones with a GIA or IGI certificate. These certificates guarantee authenticity and list the grading of each stone. The labs mentioned specialise in diamonds over 0.2 carat and are the world’s leading diamond authentication laboratories.
