This 4.51ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG630453804 or 630453804. Listed at 21 retailers as of October 30, 2026, with prices from €945 to €5,138, a €4,193 spread on the same certified stone. Rare Carat lists it at €5,138. 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.
