About this 0.41ct lab-grown round diamond

This 0.41ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LGF6G20530 or F6G20530. Listed at 2 retailers as of October 31, 2026, with prices from $653 to $1,106, a $453 spread on the same certified stone. 18carati lists it at $1,106. 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.
