About this 1.86ct lab-grown emerald diamond

This 1.86ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG508155760 or 508155760. Listed at 3 retailers as of October 28, 2026, with prices from £850 to £1,116, a £266 spread on the same certified stone. Rare Carat lists it at £1,116. 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.
