This 1.63ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG741531006 or 741531006. Listed at 20 retailers as of October 28, 2026, with prices from £176 to £1,532, a £1,355 spread on the same certified stone. Brilliant Earth lists it at £1,532. 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.
