About this 1.37ct lab-grown cushion diamond

This 1.37ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG436045625 or 436045625. Listed at 9 retailers as of October 29, 2026, with prices from £258 to £1,153, a £895 spread on the same certified stone. MOH London lists it at £1,153. 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.
