About this 1.17ct lab-grown asscher diamond

This 1.17ct 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 LG840629951 or 840629951. Listed at 11 retailers as of October 29, 2026, with prices from £225 to £1,855, a £1,630 spread on the same certified stone. Brilliant Earth lists it at £1,855. 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.
