About this 1.53ct lab-grown cushion diamond

This 1.53ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG551291044 or 551291044. Listed at 5 retailers as of October 26, 2026, with prices from £259 to £809, a £551 spread on the same certified stone. MOH London lists it at £809. 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.
