About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839611604 or 839611604. Listed at 17 retailers as of October 25, 2026, with prices from £119 to £756, a £638 spread on the same certified stone. Reve Diamonds lists it at £756. 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.
