About this 4.97ct lab-grown asscher diamond

This 4.97ct lab-grown asscher sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG754594679 or 754594679. Listed at 15 retailers as of October 31, 2026, with prices from £5,633 to £27,660, a £22,027 spread on the same certified stone. Michael Trio lists it at £27,660. 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.
