About this 0.33ct lab-grown radiant diamond

This 0.33ct lab-grown radiant sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG778617125 or 778617125. Listed at 16 retailers as of October 29, 2026, with prices from $268 to $1,806, a $1,539 spread on the same certified stone. MOH London lists it at $1,806. 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.
