About this 0.43ct lab-grown radiant diamond

This 0.43ct lab-grown radiant sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG771601047 or 771601047. Listed at 19 retailers as of October 27, 2026, with prices from $258 to $1,658, a $1,400 spread on the same certified stone. MOH London lists it at $1,658. 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.
