This 4.05ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG843651164 or 843651164. Listed at 16 retailers as of October 31, 2026, with prices from €541 to €4,538, a €3,997 spread on the same certified stone. Brilliant Earth lists it at €4,538. 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.
