About this 3.03ct lab-grown emerald diamond

This 3.03ct lab-grown emerald sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG468103921 or 468103921. Listed at 9 retailers as of November 4, 2026, with prices from £357 to £1,256, a £899 spread on the same certified stone. MOH London lists it at £1,256. 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.
