About this 0.82ct lab-grown radiant diamond

This 0.82ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818658698 or 818658698. Listed at 18 retailers as of October 29, 2026, with prices from $358 to $1,603, a $1,245 spread on the same certified stone. MOH London lists it at $1,603. 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.
