This 1.45ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG677563845 or 677563845. Listed at 14 retailers as of October 28, 2026, with prices from $367 to $2,909, a $2,543 spread on the same certified stone. Do Amore Diamonds lists it at $2,909. 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.
