About this 3.03ct lab-grown cushion diamond

This 3.03ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840657036 or 840657036. Listed at 11 retailers as of October 31, 2026, with prices from £382 to £1,873, a £1,491 spread on the same certified stone. Brilliant Earth lists it at £1,873. 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.
