About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG686501524 or 686501524. Listed at 16 retailers as of October 28, 2026, with prices from €142 to €1,324, a €1,182 spread on the same certified stone. Queensmith lists it at €1,324. 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.
