About this 1.42ct lab-grown asscher diamond

This 1.42ct 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 LG840634346 or 840634346. Listed at 13 retailers as of October 30, 2026, with prices from £381 to £2,776, a £2,395 spread on the same certified stone. Brilliant Earth lists it at £2,776. 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.
