About this 0.41ct lab-grown round diamond

This 0.41ct lab-grown round 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 LG816668674 or 816668674. Listed at 15 retailers as of October 26, 2026, with prices from $171 to $1,775, a $1,605 spread on the same certified stone. MOH London lists it at $1,775. 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.
