About this 4.09ct lab-grown asscher diamond

This 4.09ct 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 LG754508234 or 754508234. Listed at 15 retailers as of October 30, 2026, with prices from £4,503 to £19,835, a £15,332 spread on the same certified stone. With Clarity lists it at £19,835. 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.
