This 3.04ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG771624970 or 771624970. Listed at 17 retailers as of October 31, 2026, with prices from £396 to £4,791, a £4,395 spread on the same certified stone. Brilliant Earth lists it at £4,791. 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.
