About this 1.49ct lab-grown cushion diamond

This 1.49ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6525871312. Listed at 3 retailers as of November 4, 2026, with prices from £726 to £874, a £148 spread on the same certified stone. Kay Jewelers lists it at £874. 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.
