About this 1.38ct lab-grown cushion diamond

This 1.38ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG569301353 or 569301353. Listed at 3 retailers as of October 31, 2026, with prices from £666 to £918, a £252 spread on the same certified stone. Kay Jewelers lists it at £918. 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.
