About this 1.05ct lab-grown asscher diamond

This 1.05ct lab-grown asscher sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831679991 or 831679991. Listed at 13 retailers as of November 3, 2026, with prices from £201 to £1,215, a £1,014 spread on the same certified stone. Brilliant Earth lists it at £1,215. 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.
