About this 4.05ct lab-grown cushion diamond

This 4.05ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG840657039 or 840657039. Listed at 17 retailers as of November 2, 2026, with prices from €696 to €4,708, a €4,011 spread on the same certified stone. Brilliant Earth lists it at €4,708. 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.
