About this 0.37ct lab-grown radiant diamond

This 0.37ct 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 LG663403458 or 663403458. Listed at 13 retailers as of October 30, 2026, with prices from $261 to $1,317, a $1,056 spread on the same certified stone. MOH London lists it at $1,317. 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.
