About this 0.53ct lab-grown radiant diamond

This 0.53ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG815646173 or 815646173. Listed at 16 retailers as of November 5, 2026, with prices from $195 to $2,026, a $1,831 spread on the same certified stone. MOH London lists it at $2,026. 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.
