This 4.09ct lab-grown asscher sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG539204849 or 539204849. Listed at 2 retailers as of October 30, 2026, with prices from €676 to €870, a €194 spread on the same certified stone. Adiamor lists it at €870. 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.
