About this 1.5ct lab-grown asscher diamond

This 1.5ct lab-grown asscher sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG779633924 or 779633924. Listed at 12 retailers as of October 30, 2026, with prices from €166 to €837, a €671 spread on the same certified stone. Rare Carat lists it at €837. 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.
