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 LG818653751 or 818653751. Listed at 22 retailers as of October 30, 2026, with prices from £1,937 to £12,609, a £10,673 spread on the same certified stone. With Clarity lists it at £12,609. 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.
