About this 1.2ct lab-grown emerald diamond

This 1.2ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG559279332 or 559279332. Listed at 17 retailers as of October 30, 2026, with prices from £189 to £905, a £716 spread on the same certified stone. Reve Diamonds lists it at £905. 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.
