About this 1.05ct lab-grown emerald diamond

This 1.05ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG621495340 or 621495340. Listed at 21 retailers as of October 27, 2026, with prices from £170 to £959, a £789 spread on the same certified stone. Reve Diamonds lists it at £959. 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.
