This 4.01ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG447069257 or 447069257. Listed at 10 retailers as of November 5, 2026, with prices from $1,336 to $8,327, a $6,991 spread on the same certified stone. Do Amore Diamonds lists it at $8,327. 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.
