About this 0.83ct lab-grown radiant diamond

This 0.83ct 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 LG818658803 or 818658803. Listed at 19 retailers as of November 5, 2026, with prices from $646 to $2,860, a $2,214 spread on the same certified stone. MOH London lists it at $2,860. 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.
