About this 1.98ct lab-grown cushion diamond

This 1.98ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG820604247 or 820604247. Listed at 3 retailers as of November 3, 2026, with prices from £222 to £874, a £652 spread on the same certified stone. Brilliance 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.
