This 3.01ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG750529174 or 750529174. Listed at 6 retailers as of November 1, 2026, with prices from $1,319 to $3,527, a $2,208 spread on the same certified stone. Rare Carat lists it at $3,527. 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.
