This 1.35ct 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 standard cut grade and certified by IGI LG625437503 or 625437503. Listed at 11 retailers as of October 30, 2026, with prices from €277 to €2,193, a €1,915 spread on the same certified stone. Do Amore Diamonds lists it at €2,193. 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.
