About this 1.39ct lab-grown cushion diamond

This 1.39ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG593372543 or 593372543. Listed at 9 retailers as of November 2, 2026, with prices from £325 to £831, a £507 spread on the same certified stone. MOH London lists it at £831. 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.
