About this 1.29ct lab-grown cushion diamond

This 1.29ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG742502165 or 742502165. Listed at 14 retailers as of October 28, 2026, with prices from £163 to £883, a £720 spread on the same certified stone. Reve Diamonds lists it at £883. 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.
