This 1.06ct lab-grown heart 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 LG836619130 or 836619130. Listed at 17 retailers as of October 27, 2026, with prices from £297 to £1,690, a £1,393 spread on the same certified stone. Brilliant Earth lists it at £1,690. 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.
