About this 4.05ct lab-grown cushion diamond

This 4.05ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG804668748 or 804668748. Listed at 17 retailers as of October 31, 2026, with prices from €837 to €5,263, a €4,426 spread on the same certified stone. Brilliant Earth lists it at €5,263. 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.
