About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825634225 or 825634225. Listed at 18 retailers as of October 30, 2026, with prices from £188 to £1,254, a £1,066 spread on the same certified stone. Brilliant Earth lists it at £1,254. 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.
