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 VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG618484830 or 618484830. Listed at 14 retailers as of October 29, 2026, with prices from £476 to £2,307, a £1,831 spread on the same certified stone. MOH London lists it at £2,307. 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.
