About this 0.54ct lab-grown cushion diamond

This 0.54ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407932277 or 407932277. Listed at 6 retailers as of November 5, 2026, with prices from £232 to £1,191, a £959 spread on the same certified stone. MOH London lists it at £1,191. 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.
