This 6.5ct lab-grown radiant sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG818626143 or 818626143. Listed at 9 retailers as of November 1, 2026, with prices from €1,203 to €4,990, a €3,787 spread on the same certified stone. With Clarity lists it at €4,990. 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.
