When I first heard about Altered Carbon and their lab-grown diamond jewellery, I was curious but cautious. Lab-grown diamonds have come a long way, but quality can vary widely between brands. After wearing and evaluating pieces from Altered Carbon, here’s my honest take on the diamond quality. From the moment I received my jewellery, the first impression was strong. The diamonds had a bright, appealing sparkle — the kind you’d expect from high-quality stones. In good lighting, they reflected light well and didn’t appear dull or flat. This was reassuring, especially because one of the biggest concerns many buyers have with lab-grown diamonds is that they look “less lively” than they should. In my case, the brilliance was certainly there.The cut quality played a major role in the overall look. The diamonds I received were well-cut, with balanced proportions that maximized their brilliance. There were no obvious light leakage issues or odd reflections — something that can happen when cuts are poorly done. Even without a jeweller’s loupe, they looked clean and sharp to the naked eye.
