About this 3ct lab-grown asscher diamond

This 3ct lab-grown asscher sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG821639576 or 821639576. Listed at 13 retailers as of October 30, 2026, with prices from £2,605 to £13,662, a £11,057 spread on the same certified stone. With Clarity lists it at £13,662. 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.
