This 1.45ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG617452366 or 617452366. Listed at 8 retailers as of November 1, 2026, with prices from $295 to $2,404, a $2,109 spread on the same certified stone. Do Amore Diamonds lists it at $2,404. 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.
