About this 3.09ct lab-grown asscher diamond

This 3.09ct 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 LG780663641 or 780663641. Listed at 14 retailers as of October 29, 2026, with prices from £2,672 to £10,490, a £7,818 spread on the same certified stone. With Clarity lists it at £10,490. 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.
