About this 4.04ct lab-grown cushion diamond

This 4.04ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG654458481 or 654458481. Listed at 3 retailers as of October 28, 2026, with prices from $1,740 to $4,034, a $2,294 spread on the same certified stone. Rare Carat lists it at $4,034. 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.
