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 7346836777. Listed at 3 retailers as of October 29, 2026, with prices from €452 to €850, a €399 spread on the same certified stone. MOH London lists it at €850.
