This 0.4ct lab-grown round sits in the sub-half-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by GIA 6251609794. Listed at 3 retailers as of October 26, 2026, with prices from $509 to $956, a $448 spread on the same certified stone. MOH London lists it at $956.
