This 1.06ct 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 LG831679989 or 831679989. Listed at 18 retailers as of November 3, 2026, with prices from £164 to £1,230, a £1,066 spread on the same certified stone. Brilliant Earth lists it at £1,230. 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.
