About this 1.05ct lab-grown asscher diamond

This 1.05ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG837622454 or 837622454. Listed at 19 retailers as of October 27, 2026, with prices from £198 to £1,367, a £1,168 spread on the same certified stone. Brilliant Earth lists it at £1,367. 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.
