This 4.31ct lab-grown cushion 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 LG564385689 or 564385689. Listed at 11 retailers as of November 1, 2026, with prices from $772 to $4,809, a $4,037 spread on the same certified stone. Brilliant Earth lists it at $4,809. 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.
