This 1.64ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG826606966 or 826606966. Listed at 17 retailers as of October 28, 2026, with prices from £397 to £1,900, a £1,503 spread on the same certified stone. Brilliant Earth lists it at £1,900. 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.
