About this 0.55ct lab-grown radiant diamond

This 0.55ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG788635092 or 788635092. Listed at 18 retailers as of October 29, 2026, with prices from $202 to $1,177, a $975 spread on the same certified stone. MOH London lists it at $1,177. 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.
