This 1.54ct lab-grown radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG570363627 or 570363627. Listed at 15 retailers as of October 30, 2026, with prices from €171 to €990, a €819 spread on the same certified stone. MOH London lists it at €990. 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.
