About this 1.03ct lab-grown emerald diamond

This 1.03ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830619036 or 830619036. Listed at 12 retailers as of October 28, 2026, with prices from £181 to £1,468, a £1,287 spread on the same certified stone. Brilliant Earth lists it at £1,468. 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.
