About this 4.9ct lab-grown cushion diamond

This 4.9ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG788652930 or 788652930. Listed at 17 retailers as of October 29, 2026, with prices from £1,430 to £8,075, a £6,645 spread on the same certified stone. Do Amore Diamonds lists it at £8,075. 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.
