About this 2.55ct lab-grown emerald diamond

This 2.55ct lab-grown emerald sits in the two to three carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835685305 or 835685305. Listed at 21 retailers as of October 31, 2026, with prices from £588 to £4,023, a £3,435 spread on the same certified stone. Brilliant Earth lists it at £4,023. 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.
