About this 3.04ct lab-grown cushion diamond

This 3.04ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838615400 or 838615400. Listed at 13 retailers as of October 28, 2026, with prices from £561 to £3,542, a £2,980 spread on the same certified stone. Brilliant Earth lists it at £3,542. 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.
