About this 0.4ct lab-grown round diamond

This 0.4ct lab-grown round sits in the sub-half-carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LGY-24800 or Y-24800. Listed at 3 retailers as of November 3, 2026, with prices from €453 to €709, a €256 spread on the same certified stone. Fonder Diamond lists it at €709. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
