About this 1.57ct lab-grown cushion diamond

This 1.57ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG570337149 or 570337149. Listed at 2 retailers as of October 31, 2026, with prices from €778 to €1,023, a €245 spread on the same certified stone. The Diamond Guys lists it at €1,023. 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.
