About this 2.3ct lab-grown cushion diamond

This 2.3ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG727564795 or 727564795. Listed at 14 retailers as of October 30, 2026, with prices from £448 to £1,576, a £1,128 spread on the same certified stone. Taylor and Hart lists it at £1,576. 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.
