About this 0.55ct lab-grown radiant diamond

This 0.55ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818658675 or 818658675. Listed at 21 retailers as of November 4, 2026, with prices from €144 to €910, a €766 spread on the same certified stone. Reve Diamonds lists it at €910. 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.
