About this 0.99ct lab-grown emerald diamond

This 0.99ct lab-grown emerald sits in the just-under-one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG546228454 or 546228454. Listed at 17 retailers as of October 27, 2026, with prices from £146 to £825, a £678 spread on the same certified stone. Queensmith lists it at £825. 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.
