About this 0.7ct lab-grown cushion diamond

This 0.7ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG464189347 or 464189347. Listed at 4 retailers as of October 28, 2026, with prices from £204 to £863, a £660 spread on the same certified stone. MOH London lists it at £863. 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.
