This 0.8ct lab-grown radiant sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG389919523 or 389919523. Listed at 11 retailers as of November 5, 2026, with prices from €430 to €2,364, a €1,934 spread on the same certified stone. MOH London lists it at €2,364. 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.
