About this 0.55ct lab-grown emerald diamond

This 0.55ct 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 LG643411990 or 643411990. Listed at 21 retailers as of October 29, 2026, with prices from £166 to £1,075, a £908 spread on the same certified stone. Do Amore Diamonds lists it at £1,075. 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.
