This 0.57ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG842606071 or 842606071. Listed at 13 retailers as of November 1, 2026, with prices from $226 to $2,099, a $1,873 spread on the same certified stone. MOH London lists it at $2,099. 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.
