About this 1.66ct lab-grown cushion diamond

This 1.66ct lab-grown cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG512203187 or 512203187. Listed at 11 retailers as of October 31, 2026, with prices from €267 to €1,061, a €794 spread on the same certified stone. Brilliant Earth lists it at €1,061. 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.
