About this 1.74ct lab-grown cushion diamond

This 1.74ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG686508614 or 686508614. Listed at 13 retailers as of October 26, 2026, with prices from £342 to £1,111, a £770 spread on the same certified stone. Brilliant Earth lists it at £1,111. 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.
