About this 2.74ct lab-grown cushion diamond

This 2.74ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG784646426 or 784646426. Listed at 7 retailers as of October 29, 2026, with prices from £1,158 to £5,433, a £4,275 spread on the same certified stone. Brilliant Earth lists it at £5,433. 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.
