This 3.46ct lab-grown round sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG621488357 or 621488357. Listed at 12 retailers as of October 29, 2026, with prices from €496 to €2,295, a €1,799 spread on the same certified stone. MOH London lists it at €2,295. 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.
