About this 0.52ct lab-grown radiant diamond

This 0.52ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818657652 or 818657652. Listed at 18 retailers as of October 30, 2026, with prices from €193 to €1,048, a €855 spread on the same certified stone. Reve Diamonds lists it at €1,048. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
