About this 1.5ct lab-grown cushion diamond

This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG526271751 or 526271751. Listed at 16 retailers as of November 4, 2026, with prices from €205 to €1,118, a €913 spread on the same certified stone. Brilliant Earth lists it at €1,118. 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.
