This 4.02ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG818675296 or 818675296. Listed at 13 retailers as of October 31, 2026, with prices from $970 to $3,344, a $2,374 spread on the same certified stone. MOH London lists it at $3,344. 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.
