About this 1.25ct lab-grown cushion diamond

This 1.25ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825665019 or 825665019. Listed at 7 retailers as of November 1, 2026, with prices from £493 to £2,183, a £1,690 spread on the same certified stone. Do Amore Diamonds lists it at £2,183. 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.
