About this 0.37ct lab-grown round diamond

This 0.37ct lab-grown round 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 LG649457807 or 649457807. Listed at 18 retailers as of October 26, 2026, with prices from $146 to $1,477, a $1,331 spread on the same certified stone. MOH London lists it at $1,477. 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.
