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 VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG640442389 or 640442389. Listed at 18 retailers as of October 30, 2026, with prices from £118 to £790, a £672 spread on the same certified stone. Reve Diamonds lists it at £790. 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.
