About this 1.25ct lab-grown asscher diamond

This 1.25ct lab-grown asscher 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 LG831682814 or 831682814. Listed at 6 retailers as of October 29, 2026, with prices from £487 to £1,440, a £953 spread on the same certified stone. MOH London lists it at £1,440. 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.
