About this 0.66ct lab-grown radiant diamond

This 0.66ct 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 LG811623474 or 811623474. Listed at 19 retailers as of November 1, 2026, with prices from €220 to €1,095, a €875 spread on the same certified stone. MOH London lists it at €1,095. 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.
