About this 1.03ct lab-grown asscher diamond

This 1.03ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653921 or 818653921. Listed at 12 retailers as of October 27, 2026, with prices from £150 to £1,614, a £1,464 spread on the same certified stone. Brilliant Earth lists it at £1,614. 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.
