This 1.5ct lab-grown radiant sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG570375731 or 570375731. Listed at 17 retailers as of October 30, 2026, with prices from €163 to €1,050, a €887 spread on the same certified stone. Flawless Fine Jewelry lists it at €1,050. 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.
