This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG727578015 or 727578015. Listed at 21 retailers as of October 29, 2026, with prices from £157 to £1,015, a £858 spread on the same certified stone. Do Amore Diamonds lists it at £1,015. 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.
