About this 0.4ct lab-grown radiant diamond

This 0.4ct 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 LG652486735 or 652486735. Listed at 18 retailers as of October 26, 2026, with prices from $173 to $1,109, a $936 spread on the same certified stone. MOH London lists it at $1,109. 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.
