This 1.45ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG685501147 or 685501147. Listed at 15 retailers as of November 3, 2026, with prices from €217 to €1,535, a €1,319 spread on the same certified stone. Brilliant Earth lists it at €1,535. 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.
