About this 1.54ct lab-grown emerald diamond

This 1.54ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG825655200 or 825655200. Listed at 20 retailers as of November 4, 2026, with prices from £164 to £829, a £665 spread on the same certified stone. With Clarity lists it at £829. 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.
