About this 1.55ct lab-grown cushion diamond

This 1.55ct 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 LG642469463 or 642469463. Listed at 11 retailers as of October 29, 2026, with prices from £343 to £906, a £563 spread on the same certified stone. Brilliance lists it at £906. 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.
