How to Identify Quality in Diamond Jewellery Brands
Distinguishing true quality from clever marketing is essential when investing in high jewellery. Genuine quality rests on three pillars: independent certification, microscopic metal finishing, and a transparent buyback policy. Avoid brands that issue self-certified or in-house grading reports, as they often inflate grades.
Always insist on third-party GIA or IGI certificates with a laser-inscribed report number that you can verify online. Inspect the setting under a loupe—prongs should be perfectly rounded, metal surfaces should be flawless without casting marks, and diamonds must be set securely and evenly. Finally, a reputable brand must offer a legally binding, written lifetime exchange and buyback policy based on current market rates.
