This 1.09ct 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 LG836620218 or 836620218. Listed at 22 retailers as of October 27, 2026, with prices from £188 to £1,224, a £1,036 spread on the same certified stone. Brilliant Earth lists it at £1,224. 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.
