About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGY-22821 or Y-22821. Listed at 2 retailers as of October 30, 2026, with prices from €636 to €929, a €293 spread on the same certified stone. Fonder Diamond lists it at €929. 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.
